Injured Bolt misses rest of 2010
Tyson Gay and Usain Bolt
Tyson Gay beats Usain Bolt in the 100m in Stockholm
Olympic and world sprint champion Usain Bolt has ruled out competing for the rest of 2010 with a back injury.
The Jamaican suffered only his second professional 100m defeat on Friday when he was easily beaten by Tyson Gay at Stockholm's Diamond League meeting.
Following an examination in Germany, Bolt said: "2011 and 2012 are very important championship years and I hope to be back fully fit and healthy."
Bolt will miss the remaining Diamond League meets in Zurich and Brussels.
The triple Olympic champion was examined on Monday by a Munich doctor who found a problem with his lower back, who suggested that if not treated could cause injury to his hamstring or calf muscles.
Bolt's agent Ricky Simms said in a statement: "With a view to his future career we believe further treatment to loosen his back followed by rest will be in his best interest."
The world record holder in the 100m and 200m, along with American Gay and Asafa Powell - the three world's fastest 100m runners in history - had been scheduled to face each other at the year's final Diamond League meet in Brussels on 27 August.
Bolt has been struggling with an Achilles tendon injury and in Sweden last Friday looked far from 100% as he stuttered behind Gay in the 100m final, who cruised to victory in 9.84 seconds - just 0.02s slower than the season's fastest time.
