Back injury forces Bolt to take off the rest of 2010

Last Friday, Tyson Gay showed that despite previous evidence to the contrary, Usain Bolt was not actually invincible. The American scored a rousing upset of the world's fastest man at a meet in Stockholm, Bolt's first loss in the event since 2008. On Tuesday, Bolt's air of invincibility took another hit.

The world record holder in the 100 and 200 will call it quits for the rest of 2010 because of tightness in his lower back. His spokesman says that the condition affects Bolt's ability to generate power in his stride and could lead to leg injuries down the road. Following some treatment to loosen his back, Bolt will rest for the rest of the season before starting preparations next year for the world championships.

From the sounds of it, this is a precautionary measure and shouldn't be of concern for track fans. If it was worlds that were two weeks away instead of a meet in Zurich, it's doubtful Bolt and his people would have made the decision to shut down. It's convenient timing and allows the Jamaican to get some much needed time away from the sport before he recharges and sets his sights for worlds and the Olympics, where Tyson Gay will be waiting.
