KINGSTON- Six-time Olympic gold medallist Usain Bolt has been ruled out of Saturday's Jamaica International meeting because of a slight hamstring strain, his agent said Tuesday. The 100 and 200 metres world record holder felt tightness in training and in consultation with Coach Glen Mills decided not to risk anything at this early stage of the season, agent Ricky Simms told Reuters. "It's a small strain and he's hoping to be OK for next week. It just a problem of sprinting," Simms said. Asked if the injury was serious, Simms replied: "No. He hopes to be running in Cayman by next week, so it's what you call a grade one strain, which is you can't sprint, but you can walk OK. He's not limping or anything."–Reuters
