SYDNEY - Shane watson would be honoured to stand in for Michael clarke as Test skipper against india next month even if he thinks it's increasingly unlikely that Australia will need a caretaker captain. Australia are sweating on clarke 's hamstring injury ahead of an important three months of cricket on home soil. All rounder watson , who has had more than a few injury problems of his own in recent years, said he had spoken to clarke and the prognosis for the injury was improving. "The diagnosis is, I think, better than what it was initially, which is a great thing. It's all very positive."
