Track superstar Usain Bolt will end his competitive season early this year, citing a back injury, The Associated Press reports.

According to AP, Bolt shut down his 2010 season after visiting a doctor in Munich on August 9; he announced suffering from severe tightness in his lower back just a few days removed from falling to American track star Tyson gay in the 100-meter race of the IAAF Diamond League DN Galan.

Bolt’s manager, Ricky Simms, told AP via e-mail that the 2008 Olympic gold medalist will undergo treatment to loosen his back and rest for the 2011 and 2012 seasons.

“He has a tightness that restricts his ability to generate power in his stride and continuing to race in this condition could risk injury to his hamstrings or calf muscles,” wrote Simms, who states the decision to cut this season short is made “with a view to future career.”

“I am very disappointed to miss two of the top meetings on the circuit … but trust that it is better for me not to take any risks this year,” Bolt said via Simms, according to AP. “2011 and 2012 are very important Championship years and I hope to be back fully fit and healthy. I would like to thank everyone for their support and look forward to coming back stronger next year.”

The 6-foot 5-inch tall Jamaican hadn’t lost a race in two years until Aug. 6, when Gay edged him with a 9.84 seconds finish to Bolt’s 9.97.

Gay acknowledged that Bolt wasn’t fully healthy and wished him a well recovery.

“I wish Usain the best as he gets healthy for 2011 and 2012. I would have liked for us to race again this year, but it didn’t work out,” Gay told. “I’ve had my own injuries in the past, so I understand his decision as well as anyone.”
