Bolt Year Over Athletics
FILE - This Aug. 6, 2010, file photo shows Jamaica's Usain Bolt after his 100m heat 1 at the IAAF Diamond League ‘DN Galan’ at the Stockholm Olympic Stadium in Stockholm, Sweden. 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."
