Bolt Year Over  Athletics
FILE - This July 7, 2010, file photo shows Jamaican athlete Usain Bolt during a news conference in Lausanne, Switzerland. Bolt's manager says the Olympic track star is taking the rest of 2010 off because of tightness in his lower back. Manager Ricky Simms says in an e-mail Tuesday, Aug. 10, 2010, that Bolt has been examined by a doctor in Germany and the back problem "restricts his ability to generate power in his stride."
