Adelaide - Australia opener Simon Katich is expected to play despite an injured Achilles' tendon when the hosts begin their second innings of the second Ashes test against England.
The tourists reached 551-4 on Sunday, 306 runs ahead of Australia after no play was possible following the tea interval due to rain.
With showers forecast for the last two days, England is likely to declare early on Monday to avoid the possibility of Australia drawing the test.
"He's been pretty hindered in the field today," captain Ricky Ponting said. "He's got a sore Achilles, it's quite badly swollen so I had him on and off the ground a couple of times today to get as much ice on it as possible knowing he's got plenty of batting to do over the next couple of days.
"He's a pretty tough character and once it's time to bat he'll be available."
Australia's other opener Shane Watson also expects Katich to take the field with him when England do decide to declare.
"I'm sure he'll be all right to bat, he's a very tough man so it would take a lot for him not to bat," Watson said.
Ponting's side will have the worst of the batting conditions when they bat a second time and the Australia skipper said spinner Graeme Swann will be particularly hard to face.
"Dougie's footmarks have created a nice area for Swann so he'll be a handful on here," Ponting said. "I think we saw a hint of reverse swing as the pitch gets more abrasive. We'll have our challenges no doubt about it, but we've done it before and we'll have to do it again."
