Israel Folau is a doubt for Australia's Rugby World Cup Pool A showdown with Wales on Saturday after suffering an ankle injury in the victory over England.
The 26-year-old full-back did not train yesterday after suffering the injury in the Wallabies' 33-13 victory over England which knocked the hosts out at the group stage.
"He came off the field in the game with a bit of a sore ankle and didn't train yesterday," Wallabies attack coach Stephen Larkham told reporters. "We're going to wait and see how he pulls up today."
If Folau misses out, then Kurtley Beale is the most likely to take the number-15 shirt for Saturday's match at Twickenham.
Both sides have already reached the quarter-finals, but the loser is likely to face South Africa in the last eight, while the winner will face either Japan or Scotland.
