Jamaica's Asafa Powell - File

KINGSTON, Jamaica (AP)

World-record holder Asafa Powell resumed training yesterday after missing time with a chest injury, and should be in good health in time for the Olympics, his manager said.

Powell, who ran the 100 meters in 9.74 seconds last year to break the record, pulled a pectoral muscle last month and halted training for about two weeks.

"He's doing fine," Powell's agent, Paul Doyle, told The Associated Press. "We expect him to be 100 per cent in two weeks. It's just a matter of making up time. It shouldn't affect his Olympic preparation."

Two Saturday's ago, Powell's countryman, Usain Bolt, ran the second-fastest 100 metres ever, finishing in 9.76 seconds at the Jamaica International Invitational.

The two are expected to meet at Jamaica's national championships at the end of June. Powell will not run in the Prefontaine Classic in Oregon early next month.
