Andrew Symonds has trained strongly in Durban and appears set to return to Australia's XI for the fourth one-day international with South Africa on Friday.
The all rounder is yet to play a game in the five-match series after injuring a thigh muscle during training, but he says he is recovering well.
"I haven't been given the all-clear but it's progressing nicely," Symonds told AAP.
"It's not sort of pulling like it was and it didn't feel like it was going to go again or anything."
But he remains cautious as he has been named in the Test squad for a three-match series beginning in Cape Town next week.
"I had to be careful because if I did it again that would have probably been the end of my tour," he said.
"So I have been slightly frustrated, you might say."
Symonds added he would undergo a fitness test on Thursday night, before a final decision is made on whether he should play.
Meanwhile, Australia needs to win the two remaining matches in the one-day series to ensure victory after dropping the first two.
The tourists kept the series alive with a 24-run win on Sunday in Port Elizabeth as captain Ricky Ponting made his return from a stomach injury. He top scored with 62 runs.
"He's probably the best batter in the world at the moment. He sort of creates an aura around that Australian side as well," South Africa wicketkeeper Mark Boucher said.
"You can see when he is out on the field, when he's in charge, the guys are really up for a game."
"To lose a player like him must have been a big blow for (Australia)."
"We certainly know what it feels like. We lost a couple of players when we were in Australia."
"He's a world-class performer and a definite danger-man in their side."
