The Wallabies were due to name the side before the weekend for the Twickenham game, but held back the announcement in order for a full-contact training session to be carried out.
David Pocock has been receiving treatment for a calf injury and Israel Folau for an ankle injury. There are also questions raised regarding Scott Sio’s elbow.
Michael Cheika said all three would have to complete a full session to be considered.
“We’ll run them out today and see how we go,” he added. “It’s a World Cup semi-final so it’s not like we’re keeping anyone for next week.”
Pocock and Folau both missed last week’s game.
