Doolan called in as cover

Australia have called in Tasmanian batsman Alex Doolan as a cover for Shane Watson, who is struggling to get fit for the final Ashes Test against England that starts on Friday at the Sydney Cricket Ground.

Watson injured his groin during the Boxing Day Test in Melbourne that Australia won to make it 4-0. They are now eyeing a whitewash in Sydney.

Australia are expected to keep the successful attack, bowling coach Craig McDermott said on Monday.

Paceman Ryan Harris and all-rounder Shane Watson bowled sparingly in the second innings of the fourth Test win in Melbourne as they managed respective knee and groin complaints, raising doubts about their fitness.

Squad: Michael Clarke (captain), Brad Haddin (wicketkeeper), Chris Rogers, David Warner, Shane Watson, Alex Doolan, Steve Smith, George Bailey, James Faulkner, Mitchell Johnson, Ryan Harris, Peter Siddle, Nathan Lyon, Nathan Coulter-Nile.
