Tyson Gay Injured During 200 Meters

American sprinter Tyson Gay fell during the 200-meter dash at the U.S. Olympic trials today and was carted off the track, preventing him from qualifying for Beijing in the 200 and perhaps putting the 100 meters in doubt as well.

Gay was the world champion in both the 100 and the 200 last year, and he was expected to compete for golds in both events at this year's Olympics. Now his entire focus will go toward recuperating from what appears to be a hamstring strain in time to run the 100.

If Gay can't run in Beijing, it would be a major blow not just for him but for the Olympic Games and the sport of track and field. His showdown with Jamaican world record holder Usain Bolt was expected to be one of the marquee events of the Olympiad, and right now it's not clear whether Gay will be ready to go.
