DAEGU, South Korea — Asafa Powell has been ruled out of the 100 meters at the world championships because of a groin injury, eliminating defending champion Usain Bolt's biggest rival from the marquee event.
Powell's manager, Paul Doyle, told The Associated Press on Thursday that the injury sustained several weeks ago was still giving the fastest man of the season trouble. He added that the Jamaican could be fit by the time of the 4-by-100 relay during the final weekend of the championships.
"The groin strain is still lingering," Doyle said. "He is not quite 100 percent."
The 100-meter heats open on Saturday and the race is traditionally the highlight of the championships. It is also the opening race in Bolt's quest for three sprint gold medals.
American rival Tyson Gay was injured in June, and two other top performers are not in Daegu because of doping scandals, leaving Bolt with few credible challengers.
