World Athletics 2011: Asafa Powell pulls out of 100m Jamaican sprinter Asafa Powell has pulled out of the World Championships 100m in Daegu after failing to overcome a groin injury, according to his agent. The 28-year-old was expected to challenge world champion Usain Bolt, but has failed to shake off a problem he suffered earlier in August. Powell's withdrawal marks a blow to the men's sprints, with American Tyson Gay also missing with a hip injury. Asked if the race had lost something, Bolt said: "A lot of people are going to look at it like that but I can't because there are going to be seven other guys besides me. "They haven't come out here to say, 'Usain's the fastest man in the world, let's give him a gold medal'. They've come to win so I'm really focused and I'm ready."--I like this one! France's European 100m and 200m champion Christophe Lamaitre added: "Of course, it's very sad for Powell but I think it's a good opportunity for the rest of the sprinters."
