Sydney: All-rounder Shane Watson was on Friday included in Australia's squad for the pivotal second Test against South Africa, despite concerns about his fitness.
Vice-captain Watson sat out the first drawn Gabba Test against the world number one Proteas with a calf strain and his inclusion for next week's Adelaide clash is the only amendment to the line-up.
Rob Quiney, who was added to the squad when Watson pulled out of Brisbane, remains with the team.
National selector John Inverarity said it was not clear if Watson, who has been prolific with both bat and ball in all formats recently, would recover in time for the Test that starts on Thursday.
"Shane Watson is making steady progress from his calf injury, but it is too early to determine if he will be fit to come under consideration for selection," he said.
The Australians came out of the first of three Tests with an edge over the South Africans in the drawn game, but they must win the series to wrest the world number one ranking from their rivals, making Adelaide pivotal.
