Adelaide: Australia have overlooked injured vice-captain Shane Watson in an unchanged line-up for the second Test against South Africa starting on Thursday.
Watson missed the drawn series opener in Brisbane with a calf injury and attempted to prove his fitness at training in Adelaide this week. But captain Michael Clarke said on Wednesday that lingering doubts remained about the allrounder's injury.
Clarke said Watson had "improved a lot over the last few days ... but is probably a few days short of being 100 per cent."
Left-arm paceman Mitchell Starc will again be 12th man, Clarke said.
Australia: Michael Clarke (captain), David Warner, Ed Cowan, Rob Quiney, Ricky Ponting, Mike Hussey Matthew Wade, Peter Siddle, James Pattinson, Nathan Lyon, Ben Hilfenhaus, Mitchell Starc (12th man).
