MELBOURNE - Australia captain Michael Clarke has suffered a hamstring injury during Friday's training in Harare and is doubtful for their first one-day international against Zimbabwe on Monday. Clarke, who has had a five-month rest since leading Australia to the 2-1 Test series triumph in South Africa, experienced pain in his left hamstring while training. "We will monitor his condition closely over the next 24 hours to see how he responds to further treatment before making a decision on his management," team physiotherapist David Beakley said.–Reuters
