Josh Hazlewood is out of the competition for a place in the Australia pace attack after being struck down by a shin injury.
The youngster was one of eight fast bowlers competing for three or four places in their Ashes squad, but the New South Wales player will be out for 'several weeks' and will not be back until the third Test at the earliest.
Injuries have been a theme for Australian bowlers in recent years with James Pattinson, Mitchell Starc, Jackson Bird and Pat Cummins also out injured.
Hazlewood first experienced the shin soreness in last week's Sheffield Shield match against Tasmania and he was withdrawn from their game against Victoria at the request of Cricket Australia as part of their rotation policy.
But the injury that will now rule him out of Sydney club cricket this weekend and for the next few weeks of Shield and potentially Test cricket, only flared up after the board's announcement.
NSW fast bowling coach Geoff Lawson was vocal in his opposition to CA's decision to intervene and rest Hazlewood in the first place as he needed more first-class cricket to improve his rhythm.
Hazlewood, who has yet to make his Test debut, was part of the Australia squad for the third Test against South Africa in Perth last year before being ruled out of contention for a debut after being diagnosed with stress fractures.
Ryan Harris, who is back from a hamstring problem, Peter Siddle and Mitchell Johnson seem likely to form the bulk of their attack although there is still competition from Ben Hilfenhaus, Clint McKay, Nathan Coulter-Nile and Ben Cutting.
