were once the closest living relatives of modern humans, ranging across a vast area from Europe to western Asia and the Middle East. Their lineage went extinct about the same time modern humans expanded across the world, leading to speculation that modern humans wiped them out.

Scientists Bienvenido Martnez-Navarro and Policarp Hortol at the Catalan Institute of Human Paleoecology and Social Evolution in Tarragona, Spain, noted the migration of modern humans across the globe may have played a role in the extinction of more than 178 of the world's largest mammal species or megafauna, such as . Homo sapiens can essentially be considered "a worldwide pest species," they write in the May 8 issue of the journal Quaternary International. "No other species has ever developed such a killing potential." []

No evidence

Humans today also hunt and eat chimpanzees, gorillas and orangutans, humans' closest remaining living relatives, the researchers noted. As such, they suggest ancient modern humans may have killed and even devoured Neanderthals to extinction to get rid of competition. There is also fossil evidence that Neanderthals at timesand ancient modern humans sometimes ate other ancient modern humans, they added.

However, there is no clear evidence that ancient modern humans ever ate Neanderthals, they noted. For instance, scientists have not discovered Neanderthal bones with cut marks on them from ancient modern human stone tools.

There is even very little evidence there was any violence between ancient modern humans and Neanderthals, "and the two or three possible examples there are are controversial and can be interpreted different ways," paleoanthropologist Chris Stringer at the Natural History Museum in London, who did not take part in this study, told LiveScience. "I would not say this has been one of the mainstream arguments for ."

For instance, in Shanidar Cave in Iraq, "there's a rib wound that's suggested to be from a spear that came from above, and spear-throwing appears to be an advance linked with modern humans," Stringer said. "The problem is, we don't know if there were any modern humans in the vicinity at the time, so that could've been produced by another Neanderthal, perhaps one standing over and thrusting downward against a victim who is on the ground."

Human-Neanderthal contact?

Moreover, there is growing doubt there was ever much overlap between ancient modern humans and Neanderthals. For instance, recent findings suggestthousands of years earlier than before thought, perhaps never crossing paths with modern humans there.

"Even if Neanderthals and modern humans overlapped in terms of territory, they may not have contacted each other that much," Stringer said. "When modern humans came out of Africa, they did so in quite small groups, and they were spread out."

Recent genetic evidence suggests there was some interbreeding between ancient modern humans and Neanderthals, confirming there was at least some contact. "However, while such interactions could've been violent encounters, they could also have been peaceful as well," Stringer said. "We don't know for sure." []

When ancient modern humans encountered Neanderthals, "it may have been near the end of their time," Stringer said. "They were rather thin on the ground by then the level of genetic diversity we see in Neanderthals suggests their population size from Spain to Siberia was at most 20,000 people, which by modern standards would make them an endangered species, really."

"In my view of the Neanderthal disappearance, we don't need to invoke violent causes for their demise," Stringer said. "There are already two main factors they had to contend with."

The first factor is very rapid climate change.

"Most of the north Atlantic was switching from bitterly cold to nearly as warm as the present day every few thousand years, sometimes in less than a decade, and so Neanderthals had to deal with an extremely unstable climate in western Europe before modern humans arrived there," Stringer said.

Second, Neanderthals had to compete for resources with modern humans.

"Modern humans were hunting the same animals and wanting to live in the best real estate. You don't have to kill off other species intentionally just take over their environments, take away their food, and they die without lethal warfare."

There might have been some violent encounters between ancient modern human and Neanderthal groups, or within those groups "that's human nature, and has happened throughout history," Stringer added. "But the evidence is pretty thin that violence was a major mechanism for their disappearance."

Wuerffel and the Gators bounced back from that record-breaking 62-24 smackdown to take the title the next season.

The former quarterbacks will cross paths again in December, when they are inducted into the College Football Hall of Fame.

Wuerffel and Frazier, along with Heisman Trophy winner Ron Dayne, highlighted the latest Hall of Fame class of 12 players and two coaches announced by the National Football Foundation on Tuesday.

The rest of the players to be inducted in Manhattan are: Miami Heisman winner Vinny Testaverde, whose selection was announced Monday; Ted Brown of North Carolina State; Tedy Bruschi of Arizona; Jerry Gray of Texas; Steve Meilinger of Kentucky; Orlando Pace of Ohio State; Rod Shoate of Oklahoma; Percy Snow of Michigan State; and Don Trull of Baylor.

The new Hall of Fame coaches are Wayne Hardin, who led Navy and Temple, and Bill McCartney of Colorado.

Florida and Nebraska fans have been eagerly awaiting the inductions of their beloved All-Americans for years.

Wuerffel won the Heisman in 1996, when he led the Gators to the national championship, throwing for 3,625 yards and 39 touchdowns in coach Steve Spurrier's Fun-n-Gun offense.

"I'm thankful for what college football has meant in my life ... and how it allowed me to help other people," said Wuerffel, who appeared at a news conference with Bruschi at the Nasdaq Stock Exchange in Times Square.

Wuerffel finished his college career as one of the most prolific passers in major college football history with 10,875 yards and 114 touchdown passes.

After a short NFL career, he retired to dedicate himself to ministry work in New Orleans, where he played from 1997-99 with the Saints.

In 2011, Wuerffel was diagnosed with a rare autoimmune disorder Guillain-Barre syndrome, which causes paralysis and problems with the nervous system but is treatable.

Wuerffel said he is just about all the way back to his old self, but endured a difficult year and a half with little energy or strength.

"You're trying to live a normal life with 20 percent of your energy, 40 percent of your energy," he said.

Frazier, from Bradenton, Fla., was a four-year starter at Nebraska, running coach Tom Osborne's option attack.

"He was an outstanding leader and catalyst and made everyone around him better," Osborne said in a statement. "Tommie managed the game very well, and was a natural option quarterback. He had a good sense of timing, when to pitch, when not to pitch. He had excellent balance, good speed and was very strong.

"Tommie was better prepared to start as a freshman than any quarterback we had. That's not easy to do, but he was unusually mature and competitive."

Frazier was the centerpiece of Nebraska's last great dynasty. The Huskers were 33-3 in games he started and won back-to-back national titles in 1994 and '95.

"I think it's been a longer time coming than most of us would have thought," said former teammate Aaron Graham, a center on those great Nebraska teams. "The guy was the best college football player of our era and certainly deserving of one of the highest honors you can achieve as a college football player."

Frazier's famous tackling-breaking 75-yard touchdown run put an exclamation point on Nebraska's 62-24 victory over Wuerffel and Florida in that '96 Fiesta Bowl.

"I've seen that run a lot of times," Wuerffel said.

That loss helped propel the Gators into next season, Wuerffel said.

"I think most people would say the 1995 team was more talented," he said. "I think (the loss to Nebraska) helped that team mature."

Frazier finished second in the Heisman Trophy voting in 1995 as a senior and finished his career with 5,476 total yards of offense and 79 total touchdowns.

"You never play the game and think you are going to be in the Hall of Fame one day," Frazier said in a statement released by Nebraska. "You just go out and try to be the best you can and whatever happens, happens. I was fortunate good things happened."

Dayne is the NCAA's career rushing leader with 6,397 yards rushing, though his bowl game yards would boost his career total past 7,000 yards if he hadn't played when the NCAA did not count them in regular season stats. The burly tailback won the Heisman for the Badgers in 1999.

"In my opinion, Ron was simply the most dominant running back that ever played college football," said Dayne's former coach and current Wisconsin athletic director Barry Alvarez in a statement.

Bruschi had 52 sacks as part of Arizona's Desert Swarm defenses during the mid-1990s.

"I don't know who came up with that nickname, but thank you," Bruschi said.

Cadila, India's sixth-largest drugmaker by sales, spent $250 million developing Lipaglyn, a new chemical entity or new discovery, and aims to spend another $150 million to $200 million to launch the drug outside India, the company's chairman, Pankaj Patel, said.

"We expect this to be a blockbuster drug, which means over $1 billion sales a year" when the drug is sold globally, he told a news conference. For now the company is hoping for Lipaglyn sales of 1 billion rupees ($17.7 million) in India over three years, he said.

Cadila took about eight years to develop the molecule and conducted clinical trials on more than 1,000 patients in India, Patel said.

The company plans to launch two other new chemical entities in the next seven years and has eight drugs in various stages of clinical development, he added.

Traders on Tuesday had driven up the company's shares by 5.2 percent in anticipation the company would make a bigger announcement than the drug approval on Wednesday such as a stake buy and drove the shares down 4.2 percent in afternoon trading.

Although the one-day conference was a response to gun violence, its agenda is much broader and includes discussion of insurance coverage for mental health care and substance abuse, recognizing the signs of mental illness in young people and improved access to services for veterans. The overall goal is reducing the stigma of mental health problems and encouraging those who are struggling to get help.

Obama plans to deliver opening remarks in the East Room and Vice President Joe Biden, the president's point man on gun violence, is scheduled to close it from the Eisenhower Executive Office Building. Around 150 invited attendees include mental health advocates and patients, educators, health care providers, faith leaders, lawmakers and local government officials from across the country.

Cooper and Close bring their advocacy and a celebrity buzz to the event.

Cooper has been promoting mental health awareness since his Oscar-nominated leading role as a man with bipolar disorder in last year's "Silver Linings Playbook," and plans to help Biden and Veterans Affairs Secretary Eric Shinseki close the conference.

Close said Monday that her experience is "a family affair." Her sister, Jessie, was diagnosed with bipolar disorder at 51 and Jessie's son, Calen, was diagnosed with schizoaffective disorder at 19. In 2009, Close's family battles led her to help start a non-profit called Bring Change 2 Mind, which produces public service announcements to fight the stigma and discrimination associated with mental illness. She is listed on a panel discussion on how to address negative attitudes about mental illness.

"What's important is social inclusion. There's a lot of stigma," Close said in an interview Monday morning with MSNBC from the White House briefing room. She said her nephew feels his brain is healing and that he's "living a full and wonderful life." Close said her sister is doing well, "but what it would have meant to her if she had early diagnosis."

"We need people living with mental illness with the courage to say this is what I am living with. I can talk about this," Close said.

The conference comes after Obama's defeat on gun control legislation. Unable to get Congress to approve background checks, an assault weapons ban and other limits on firearms, the president has vowed to do what he can through executive action.

Among 23 executive orders Obama signed in response to the shooting at Connecticut's Sandy Hook Elementary School that killed 26 was a directive that Health and Human Services Secretary Kathleen Sebelius and Education Secretary Arne Duncan launch a national dialogue on mental health. The conference is part of that, with Sebelius hosting the panel on addressing negative attitudes and Duncan moderating a session on successful mental health outreach efforts.

There's been little publicly revealed about the mental health of Sandy Hook shooter Adam Lanza, although it's been documented that other gunmen involved in mass shootings suffered from mental illness. Federal law bans certain mentally ill people from purchasing firearms, but the background check system is woefully incomplete and Obama is trying to get more mental health records included.

In announcing the conference, the White House stressed that the vast majority of people with mental health conditions are not violent and are more likely to be victims than perpetrators of crimes. But the need to improve the country's mental health care system is something all sides of the gun debate have advocated, including the National Rifle Association.

"That is something substantive that Congress and the president could do right now that would actually help prevent future tragedies, unlike the gun control proposals that the president unsuccessfully tried to push through Congress," said NRA spokesman Andrew Arulanandam

The White House said Obama plans to announce that the Department of Veterans Affairs will conduct mental health summits nationwide to increase awareness of VA programs and link veterans and their families with community resources to support their needs. The conference also plans to tout improvements in mental health coverage under Obama's health care law, including a ban beginning next year against denying coverage to those who are mentally ill.

The White House also plans to focus on commitments being made in the private sector to increase understanding and awareness, including a campaign by the National Association of Broadcasters through television and radio ads and social media. Several organizations that work with young people also are planning to make new commitments, including high school principals holding mental health assemblies, to YMCA instructing staff and camp counselors to recognize the signs of mental health issues in kids, to religious leaders launching conversations on the issue.

DUBLIN, Ohio (Reuters) - Luke Donald gave himself a timely boost for next week's U.S. Open at Merion Golf Club by piling up 13 birdies in his last two rounds at the Memorial Tournament, which ended at Muirfield Village on Sunday.

The former world number one has not produced winning form so far this season but believes his game is running into good shape as he prepares for the year's second major championship.

"I made a lot of birdies in the last two rounds, my game is coming around," the Englishman told Reuters after closing with a two-under-par 70 in the PGA Tour event hosted by tournament founder Jack Nicklaus.

"Just a few too many mistakes so I've got to tidy up my control with the irons, keep hitting greens. I feel like I am putting better now."

Donald recorded six birdies in the third round and seven on Sunday on a challenging layout which had posed all sorts of problems for the players during the week, mainly because of lightning-fast greens.

In the final round, the gusting winds were not as severe and fickle as they had been on Friday and Saturday at Muirfield Village Golf Club, and he was delighted to take advantage.

"I am excited about where my game is heading," said Donald, who finished tied for 21st at one under.

"I certainly feel this year my play has been better than my scores and in previous years it has almost been the opposite. I have generally scored really well through a great short game.

"That's why I have never been too worried about some of my form this year because I feel as a player that I am hitting it pretty well. I'm just waiting for some things to happen, kind of fall into place."

Donald has recorded two top-10s in seven starts on the 2013 PGA Tour, his best finish a tie for third at the RBC Heritage in April.

On the European Tour, where he has won seven titles during his career, he missed the cut at the Malaysian Open in March and also at last month's flagship BMW PGA Championship.

U.S. OPEN SIMILARITIES

Asked how much he could draw upon his week at Memorial going into the year's second major, Donald replied: "There are some similarities with fast slopey greens where you can miss in the wrong places.

"Those are similar characteristics to a U.S. Open so it's switching your brain in the right direction in terms of that and how to manage your way round the golf course.

"I made a few mental errors with some misses (at the Memorial) but I think all that is good. It engages your brain in the right way."

The U.S. Open returns to the iconic Merion Golf Club in Ardmore, Pennsylvania for the first time since 1981, and Donald looks forward to the challenge of a layout measuring only 6,996 yards off the back tees.

"There's a mixture of some very long holes with some very short holes, so it has a good variety," the 35-year-old smiled. "Short game and wedges is going to be a priority. If I can do that well, then hopefully I will have a good week."

Perhaps surprisingly for many golf fans who regard Donald as a straight-shooter with a stellar short game, the Englishman does not have a particularly impressive U.S. Open record.

He has three missed cuts and one withdrawal in nine starts, no top-10s and a best finish of joint 12th in the 2006 Open at Winged Foot.

"I always think there is a little bit of a misunderstanding of how people perceive me and how I perceive myself," said Donald, who has yet to win a major title.

"I perceive myself as someone who is a really good short-game player, gets a lot out of my game but not necessarily someone who hits a lot of fairways and hits a lot of greens.

"Maybe in my early career I was a bit more like that but nowadays I am known more for my short game prowess. That would really explain my U.S. Open record. At the U.S. Open, you really have to have great ball control to be able to contend."

FIFA approved sterner punishments at its annual congress Friday following recent problems in Italy and England. The new regulations say serious or repeat offenses by a club or its fans could also lead to a team being banned from a tournament, such as the Champions League.

The measures, which were passed by a 99 percent majority in a secret ballot of FIFA member countries, also dictate that players or officials found guilty of racist abuse in any game should be banned for at least five matches. The banned player or official will also be prevented from attending any soccer stadium during that sanction.

"We are doing something now," FIFA President Sepp Blatter said following the vote.

AC Milan player Kevin-Prince Boateng walked off the field during an exhibition game against a lower-tier team after abuse from fans, while an Italian league match between Milan and Roma was stopped because of racist chanting toward Milan's black players from Roma fans.

That led FIFA to set up an anti-racism task force under Jeffrey Webb, a FIFA vice president and the president of CONCACAF, with a mandate to look at stricter sanctions.

After the resolution was passed by FIFA's congress, it is now up to its 209 member countries to individually apply and enforce it.

UEFA has endorsed a tougher 10-match ban for racist abuse in matches in European competitions.

NASCAR spokesman Kerry Tharp told The Associated Press on Monday that there were no plans to use the system at upcoming races "so we'll have ample time to review."

Fox indefinitely suspended use of the system after the nylon rope fell onto the track about a quarter of the way through Sunday's 600-mile race. Charlotte Motor Speedway said 10 people were injured when part of the rope landed in the grandstand; three were taken to hospitals. All were checked out and released soon after.

Several drivers, including then-leader Kyle Busch, reported damage to their cars from the rope.

Fox was expected to release more information about the breakdown later Monday. The network said the system was used successfully at the Daytona 500 and last week's Sprint All-Star race in Charlotte.

Fox's final NASCAR telecast this year comes Sunday at Dover International Speedway.

Tharp said NASCAR would let the network determine what went wrong.

"We'll sync up with them on what they have learned this week and go from there," he said.

The network explained how the drive rope moves the camera back and forth and failed near its turn one connection. The camera, it said in a statement, did not come down "because the guide ropes acted as designed."

The pictures such cameras provide can be extraordinary. But in this case, the failure brought confusion and chaos to the racers and the fans.

Coca-Cola 600 winner Kevin Harvick thought he was imagining things when he noticed the black rope on the track. He was among the lucky ones who escaped without damage. Busch said he heard a "thunk" when he ran over it and knew he'd have problems.

Busch used a cellphone to take a picture of the mangled metal around his front, right-side wheel so his team could figure out how to repair the damage.

Marcos Ambrose dragged a piece of the rope that got caught up in his car behind him on the track. Mark Martin also reported problems after driving over the rope.

NASCAR red-flagged the race for about 30 minutes and allowed teams back to their pits to get their cars back to race trim.

NASCAR first threw a caution flag before two red flags came out. It eventually allowed the cars to come into the pits, giving crews 15 minutes to work on their cars.

During the break, Busch's crew frantically worked to repair several problems to the right front wheel well. After completing repairs, the crew slapped high-fives as the car rolled back on the track.

Busch remained competitive and was running in the top five at the midpoint of the race. But his night ended in frustration when his engine blew up on lap 253. He said the engine problem was not related the rope damage. He thanked NASCAR for how it handled the unique stoppage.

"I commend NASCAR for taking the initiative and letting us repair our damaged cars from the issue we had," Busch said.

Busch said he never saw the nylon rope.

Ambrose wound up ninth behind Harvick, the second top-10 finish of the year for the Richard Petty Motorsports team.

Kasey Kahne led 156 laps, most of the night, and was second to Harvick. He was as bewildered as everyone else with the TV cable across the track.

"I've never seen anything like it," he said. "I came around turn four, saw it wrapped around Kyle's car, hit mine. I thought I was seeing things."

The camera hung in place over the large painted logo on the grass between the start-finish line and pit road.

Fox broadcaster Chris Myers apologized during the telecast several times to fans, drivers and race teams for the disruption. The network's statement offered "a sincere 'thank you' to the staff at CMS for attending to the injuries and keep us informed on this developing situation."

Busch wasn't sure anybody had seen that happen before and offered a solution: "Maybe now we can rid of that thing."

The prestigious Institute of Medicine is recommending that schools provide opportunities for at least 60 minutes of physical activity each day for students and that PE become a core subject.

The report, released Thursday, says only about half of the nation's youngsters are getting at least an hour of vigorous or moderate-intensity physical activity every day.

Another concern, the report says, is that 44 percent of school administrators report slashing big chunks of time from physical education, arts and recess since the passage of the No Child Left Behind law in 2001 in order to boost classroom time for reading and math.

With childhood obesity on the rise about 17 percent of children ages 2 through 19 are obese and kids spending much of the day in the classroom, the chairman of the committee that wrote the report said schools are the best place to help shape up the nation's children.

"Schools for years have been responsible for various health programs such as nutrition, breakfast and lunch, immunizations, screenings," Harold W. Kohl III, a professor of epidemiology at the University of Texas School of Public Health, said in an interview with The Associated Press.

"Physical activity should be placed alongside those programs to make it a priority for us as a society," he said.

The report calls on the Education Department to recommend that PE be adopted as a core subject.

It says physical education in school is the "only sure opportunity" for youngsters to have access to activity that will help keep them healthy.

The majority of states, about 75 percent, mandate PE, according to the American Alliance for Health, Physical Education, Recreation, and Dance. But most do not require a specific amount of time for PE in school, and more than half allow exemptions or substitutions, such as marching band, cheerleading and community sports.

Many kids also aren't going to gym class at school every single day. According to the CDC, only about 30 percent of students nationwide attend PE classes five days a week.

Specifically, the report recommends:

All elementary school students should spend an average of 30 minutes each day in PE class.

Middle and high school students should spend an average of 45 minutes each day in PE class.

State and local officials should find ways get children more physical activity in the school environment.

PE isn't the sole solution, though.

The report advocates a "whole-of-school" approach where recess and before-and-after-school activities including sports are made accessible to all students to help achieve the 60-minutes-a-day recommendation for physical activity. It could be as simple as having kids walk or bike to school, or finding ways to add a physical component to math and science class lessons.

The report also cautions against taking away recess as a form of punishment, and it urges schools to give students frequent classroom breaks.

Schools can do this if they make it a priority, said Paul Roetert, CEO of the American Alliance for Health, Physical Education, Recreation, and Dance.

"We have an obligation to keep kids active," Roetert said in an interview. "We have research to show that physical activity helps kids perform better in school. It helps them focus better in the classroom ... and they behave better in school. So there are all kinds of side benefits."

Kitty Porterfield, spokeswoman for The School Superintendents Association, said nobody is opposed to physical education.

"Everybody would love to see more of it in schools," said Porterfield. "Given the testing and academic pressures for excellence on schools, often physical education slides to the bottom of the barrel."

The idea of putting more of an emphasis on physical education in schools has support in Congress.

Rep. Marcia Fudge, D-Ohio, plans to introduce the PHYSICAL Act on Thursday. It would recognize health education and physical education as core subjects within elementary and secondary schools. Reps. John Lewis, D-Ga., and Jared Polis, D-Colo., will join Fudge as co-sponsors.

SINGAPORE (AP) -- The parents of an American software engineer found dead in his Singapore apartment last year left the city-state Thursday before the end of a coroner's inquest, saying they had lost faith in the process. Their lawyer said they would push for a U.S. congressional investigation.

Rick and Mary Todd believe their son Shane Truman Todd was murdered in June 2012 and that evidence of suicide presented by Singapore police was faked.

Rick Todd told reporters at the airport before they left for their Montana home that they felt there was no point in staying. His lawyer Gloria James-Civetta said the family's departure marks a "closed chapter" with regards to their involvement in the inquest, and confirmed their plans to initiate a congressional investigation into Shane's death.

"Our next step from today is using the court of public opinion," Rick Todd said. "If our government wants to talk about industrial espionage and murder, we're more than willing to help."

Although the Todds have abandoned the inquest, Singapore's Attorney-General's Chambers confirmed that it may read out five statements from the Todd family next week.

During the inquest, state counsel presented evidence of links to suicide websites on the 31-year-old's laptop, as well as suicide letters written to his family members and loved ones.

Shane Todd's parents told The Associated Press in March that they believe he may have been murdered over his research in the U.S. into material used to make heat-resistant semiconductors, a technology with both civilian and military applications. The Todds have received assistance in the case from U.S. senators and the FBI.

Edward Harris Adelstein, a medical examiner based in Missouri who was engaged by the Todd family, has questioned the suicide finding and testified by video. On Tuesday, he withdrew evidence that Todd may have been strangled with a cord, and debated with government lawyers over his speculation that "well-trained assassins" may have been involved in Todd's death.

Medical examiners David Fowler and Valerie Rao testified Wednesday and rejected Adelstein's assassin theory. Fowler said that markings found on Todd's hands were commonly seen in hanging cases. He said he found nothing suspicious about a bruise Adelstein found on Todd's forehead.

The Todds have said that while they were in Singapore, they found a hard drive in their son's apartment that contained thousands of documents he had backed up from his work computer. After having it analyzed by a computer forensics expert, they found a draft of a project outline between the Institute of Microelectronics Shane Todd's former employer and Chinese telecom giant Huawei on the development of a device that utilized gallium nitride.

The heat-resistant material has civilian uses in products like LED screens and cellphone towers, and military applications in things like radar and satellite systems. Todd had been trained in the U.S. on proprietary equipment that produces the material but is restricted for export because of the potential military applications.

Huawei has said it had no cooperation with the Institute of Microelectronics related to gallium nitride. IME has said neither Todd nor the company was involved in any classified research.

The FBI has supported Singapore police claims that the hard drive had been handled by Singapore authorities who were checking for evidence, and not by an unknown person as previously believed.

The coroner's inquest will end May 28. The final outcome determining the cause of death will not be able to be appealed.

* Canadian DeLaet holds clubhouse lead (Updates at end of day's play)

May 24 (Reuters) - American Matt Kuchar held a one-shot lead at 10 under par after 15 holes when the weather-hit second round was suspended for the day at the Crowne Plaza Invitational in Fort Worth, Texas on Friday.

Kuchar, who clinched his fifth PGA Tour title at the WGC-Accenture Match Play Championship in February, will line up a 40-foot birdie putt at the par-three 16th when play resumes at 7:15 a.m. local (1215 GMT) on Saturday.

World number 13 Kuchar, the highest-ranked player in this week's field, raced to the turn in four-under 31 before recording his fifth birdie of the round at the par-four 14th to take over at the top.

The second round had already been suspended for just over two hours earlier in the day due to the threat of lightning at Colonial Country Club, giving the late starters no chance of completing the full 18 holes.

Overnight pacesetter Ryan Palmer, who tied the tournament record low for the opening round after a flawless 62 on Thursday, was at eight under with six holes to play after mixing three birdies with one bogey and a double-bogey.

Canadian Graham DeLaet was the leader in the clubhouse, having succumbed to the infamous "Horrible Horseshoe" before rebounding with two closing birdies to grab the early spotlight.

In pursuit of his first PGA Tour victory, the 31-year-old from Saskatchewan put a welcome smile back on his face as he carded a three-under-par 67 in overcast conditions to post a nine-under total of 131.

Americans Josh Teater (67), Jordan Spieth (67) and 2004 champion Steve Flesch (64) were tied for second, with Swede Fredrik Jacobson (67) and American Chris Stroud (66) a further stroke back at seven under.

DELAET DELIGHT

DeLaet completed his 67 before the siren sounded to halt the action, and was delighted with his overall position after going bogey-bogey-bogey on his back nine over the "Horrible Horseshoe" stretch of holes from the par-four third to the par-four fifth.

"It was disappointing to make those three bogeys in a row," DeLaet told Golf Channel after ending the day with a total of seven birdies and four bogeys.

"We got to the sixth hole and I just wanted to get the ball in the fairway and hit it in the middle of the green. I had a pretty reasonable short iron in there but I just wanted to make sure I didn't make another bogey.

"I parred six and seven, then had great birdies on eight and nine to finish and just kind of calm my nerves a little bit. I knew I was in contention ... it was definitely a great finish."

DeLaet, whose best PGA Tour finish was a tie for third at the 2010 Houston Open in his rookie season, drained a 28-footer at the par-three eighth and a 12-footer at the par-four ninth to take over at the top of the leaderboard.

"I got myself right back in it," he said. "My game feels good and I'm making some putts here the last couple of days, which always helps."

DeLaet, a three-times winner on the Canadian Tour where he clinched the order of merit title in 2009, has recorded three top-10s in 14 starts on the 2013 PGA Tour as he seeks a breakthrough victory on the ultra competitive U.S. circuit.

The cut was projected to fall at one-under 139 with 2011 Masters champion Charl Schwartzel of South Africa and former major winners David Toms and Davis Love III among those in danger of missing out. (Reporting by Mark Lamport-Stokes in Los Angeles; Editing by Frank Pingue/Greg Stutchbury)
