Wales full-back Liam Williams is set to return from concussion to face Australia in the World Cup Pool A decider at Twickenham on Saturday.
Williams missed Wales' win over Fiji after taking a blow to the head during their victory against England.
Flanker Dan Lydiate and lock Bradley Davies, who was taken off against Fiji, are "a bit battered but OK", according to forwards coach Robin McBryde.
Paul James will return to full training on Tuesday after a calf strain.
The prop was absent for the wins over Fiji and England after he was injured during the opening victory over Uruguay
