Tyson Gay is carted off the track Saturday after falling during his quarterfinal 200 heat at the Olympic Trials in Oregon. A severe cramp cost him a chance at doubling in the 100 and 200 at the Olympics.

EUGENE, ORE. ? Tyson Gay accelerated through the first curve. Then, he started flying.

His sprawl to the ground cost America’s best sprinter an Olympic spot in the 200 meters and made him look like less than a sure thing, health-wise at least, with the Beijing Games five weeks away.

Gay suffered what his manager called a severe cramp in his left hamstring at the U.S. Olympic track and field trials Saturday and had to be carted off the track. He was at his hotel later, being treated with ice.

Gay already has qualified for the Olympics in the 100 meters, but his chances at doubling are gone.

“There is no apparent damage otherwise, except for some road rash from the fall,” said Gay’s manager, Mark Wetmore. “He said he felt a little tightness before the race.”

Wetmore said Gay was getting an MRI as a precaution. Results were not immediately available.

“I’m very disappointed,” Gay said in a statement.

In the women’s 200 heats, Alyson Felix, 100 champion Muna Lee, Lauryn Williams and Torri Edwards all made it to today’s finals without much drama.
