EUGENE, Ore. — Sprinter Tyson Gay has a mild strain in a muscle in the back of his left leg but says he'll be 100 percent for his two races at the Beijing Olympics.

Gay has been told to restrict himself to light physical activity for the next two weeks. He pulled up abruptly in the first
40 meters of his 200-meter qualifying race Saturday at the U.S. Olympic track and field trials and had to be carted off the track.

He was diagnosed with a severe cramp in his hamstring, and an MRI that afternoon revealed the strain.

"I'll be 100 percent for the 100 and 400 relay," Gay said in an NBC interview Sunday.

Gay said he felt a "little tweak" in the hamstring before the race and told coach Jon Drummond, who recommended he not run. But Gay didn't take that advice.

"I thought it would go away once I warmed up," he said. "By the time I came off the blocks, 20, 25 meters into the race, my hamstring pulled up."

A statement from his representatives said he is "expected to engage in 'active rest' for up to 12-14 days, with light physical activity increasing through that period, then resume training."

Gay said doctors told him it could be as short as one week.

The only meet he's signed up for before the Olympics is the 100 meters at the London Grand Prix on July 24-25.

Gay, the defending world champion in the 100 and 200, already has qualified for the Olympic 100 meters. That competition begins Aug. 15 in Beijing. If he can run, he also would be expected to be part of the 400-meter relay team.

"I was upset," Gay said, "but then again I was still thankful it didn't happen in the 100 and I still have the chance to go to the Olympics."

Bubba Thornton, head coach of the U.S. men's team, said he saw Gay on Sunday morning.

"He has an injury, and I'm very confident that he's going to be in place when they say 'On your mark' " in Beijing, Thornton said.
