Watson sure Clarke will be fit

Australia captain Michael Clarke missed training on Tuesday but is still expected to play in this week's second Ashes Test against England.

Clarke rolled his right ankle in a warm-up at Adelaide Oval on Monday and missed Tuesday's session after waking up with soreness.

Cricket Australia tweeted: "Michael Clarke's ankle is a bit stiff and sore but he'll be OK for the Test."

CA said that Clarke, who missed Australia's recent one-day tour of India with a recurring back injury, is expected to train on Wednesday and return for the second Test beginning Thursday.

Clarke scored a century in Australia's 381-run win in the opening Ashes Test at Brisbane.

Australian all-rounder Shane Watson said Clarke's absence from training was precautionary.

"Obviously Michael batted beautifully in the first test, so his preparation was always going to be very good anyway," Watson said. "I know the medical staff and Michael are very confident. It was just giving him a break today and he'll be training flat-out tomorrow, ready to go for Thursday."

The Australians may need Clarke to bowl some spin in support of Nathan Lyon at Adelaide, where the drop-in pitch does not offer a lot of bounce for the fast bowlers and tends to play true for the batsmen.
