Bolt grounded for year

Coming off a rare loss at 100 meters, Olympic and world champion Usain Bolt is cutting his season short, saying he won’t race again in 2010 because of tightness in his lower back. The Jamaican’s manager, Ricky Simms, wrote in an e-mail Tuesday that the world record-holder at 100 and 200 meters will have treatment to loosen his back and then rest, skipping IAAF Diamond League track and field meets in Zurich on Aug. 19, and in Brussels on Aug. 27. “It is better for me not to take any risks this year,” Bolt said, according to Simms. “2011 and 2012 are very important … and I hope to be back fully fit and healthy. I … look forward to coming back stronger next year.”
