Powell to miss 100m at Worlds

Jamaica’s Asafa Powell has been ruled out of the individual 100 metres at the World Championships in Daegu with a groin injury, but hopes to run in the relay, his agent Paul Doyle has said.

The 28-year-old sprinter, fastest man in the world this year, had been expected to be one of the main challengers to defending champion and compatriot Usain Bolt at the event in South Korea.
