Peter Siddle won’t get another chance to find form ahead of the first Test after being left out of Australia’s second tour match in Worcester starting on Tuesday.

Left-arm Tasmanian quick James Faulkner gets another opportunity to impress against Worcestershire, with fellow fast bowlers Ryan Harris and Jackson Bird also getting their first chances to push for selection for the opening Test at Trent Bridge starting on Wednesday week.

Siddle struggled on the Australia A tour and, against Somerset last week, he was unable to find his rhythm.

His omission from Worcester means he’ll remain under a shadow of doubt heading into the first Test.

If Harris or Bird can snatch their opportunity, new coach Darren Lehmann might elect to go with form rather than proven experience.

Lehmann said Siddle’s reputation as a leader and workhorse for the side wouldn’t necessarily be enough to guarantee selection.

Harris is injury prone and would have to get through the Worcester game unscathed, but he’s a potential weapon who could be valuable on the fast and seaming wicket at Trent Bridge.

Siddle isn’t out of contention, though, and selectors will certainly know what he can offer.

Run-machine Chris Rogers is into the team and is likely to bat at No.3 with Ed Cowan to open alongside Shane Watson.

Allrounder Watson will also bowl in the match.

Phil Hughes has been retained in the line-up after making back-to-back half centuries against Somerset in the opening tour match.

Steve Smith has also been picked to play in the middle order, while spinner Ashton Agar will play, with Nathan Lyon 12th man.

Skipper Michael Clarke will get his second hit of the tour in a strong sign his troublesome back is in good nick heading into the Ashes.

Australians (batting order unconfirmed): Shane Watson, Ed Cowan, Chris Rogers, Michael Clarke (capt), Phil Hughes, Steve Smith, Brad Haddin, James Faulkner, Ryan Harris, Ashton Agar, Jackson Bird, Nathan Lyon (12th).
