Joey Carbery and Robbie Henshaw are the only Ireland squad members as yet ruled out for the final Autumn series clash with Australia on Saturday.
Munster out-half Carbery failed to return from a HIA during last Saturday's victory over Fiji and will complete his return to play protocols with his province, while Henshaw suffered a recurrence of a hamstring injury early in the same game and has returned to Leinster to continue his rehab.
Carbery's absence means that Jack Crowley, who made his Test debut last weekend, is expected to at least make the bench for the fixture against the Wallabies at the Aviva Stadium (8pm kick-off).
