Michael Cheika is really positive on David Pocock's chances of facing Argentina, while Scott Sio is also being monitored.
Australia head coach Michael Cheika is optimistic over David Pocock's chances of playing in Sunday's Rugby World Cup semi-final against Argentina and revealed Scott Sio is also making good progress.
Pocock was absent for the dramatic quarter-final victory over Scotland last Sunday due to a calf injury and the influential flanker was sorely missed.
Cheika expects the 27-year-old to return at Twickenham this weekend, while loosehead forward Sio is also on the mend as he battles to prove his fitness after suffering an elbow injury against Vern Cotter's men.
Israel Folau also missed the victory over Scotland, but trained on Tuesday as he steps up his recovery from an ankle injury.
"Scott Sio is moving along okay," said Cheika.
"We'll need a couple of days to check him out but we're really happy with the way he's come up today. The scan showed it wasn't as bad as it could have been, so he's moving along nicely.
"David Pocock is moving along really nicely because he's run already. I'm really positive about him playing."
Cheika was not surprised by Argentina's impressive quarter-final display against Ireland in Cardiff and knows the Wallabies must raise their game after being given a major scare by Scotland.
"What I saw of the game against Ireland - I've only seen the highlights and some specific bits - it's exactly what I expect from them." he added.
"I know what they bring and I want to make sure the focus is on our team to make sure it's all about us improving. We'll do our absolute best out there and let that talk."
