EUGENE (Oregon), July 6: World 200 metres champion Tyson Gay has a mild muscle strain in his left leg and will be unable to train at full strength for up to two weeks, his management company said on Sunday.

Gay crashed out of the US 200 metres quarter-finals on Saturday, tumbling to the track after about 40 metres in a fall that ended his hopes of competing at the distance at the Beijing Olympics.

The MRI showed a mild strain in the semitendinosus muscle, publicist Barbara Huebner said in the statement.

Light physical activity

He is expected to engage in active rest for up to 12-14 days, with light physical activity increasing through that period, and then resume training.

Gay, who will run the 100 metres and 4x100 metres relay in Beijing, is still on schedule to compete in the London Grand Prix meeting on July 25, the statement said.
