Australia head coach Michael Cheika hopes that Wallaby back-row David Pocock will be fit ahead of their semi-final clash against Argentina on Sunday.
Pocock has been superb for the Wallabies at the breakdown in the World Cup, making vital turnovers to ensure his team wins front-foot ball.
The number eight was ruled out of the quarter-final clash with Scotland after suffering a calf injury, but returned to training on Sunday and Cheika says that he is happy with his progress.
"He's moving along really nicely as well because he's run already," said Cheika.
"We’re really pleased with that, that’s a good sign.
"We won’t bring him back and say, ‘come into training lad and do everything’ just progress him through.
"I’m really positive about him playing."
The Wallabies received more good news after scans revealed that Scott Sio's elbow injury isn't as bad as initially thought. The 24-year-old might also be available for selection on Sunday, depending on his progress during training this week.
Pocock, who is leading the tournament in turnovers with ten, despite playing in only three games, was sorely missed over the weekend said flanker Sean McMahon.
"We definitely needed someone over the ball probably a bit stronger especially in the defensive side of things too," he said.
"Just to retain a bit of ball and get some back off them because Scotland did really well to get good ball running and good advantage line.
"We definitely needed a bit of ball in that area."
Cheika, however, feels that they have a lot of planning to do if they want to contain the Pumas on Sunday.
"There’s a different pattern now, it’s almost like a new tournament now," he said.
"We know we’ve got two weeks left and we’ve got to plan.
"We’re really good physically I think.
"They’ve trained hard and they’re in really good shape physically and I think that will help us as the week goes on."
The Wallabies mentor continued by saying that they will mainly be focusing on their game rather than that of the Pumas.
"We’re looking at ourselves, getting ourselves sorted out," he said.
"We’re bringing some new things in, making sure every player knows what his job is on the field and we’re going to go for it."
