The Wallabies star flanker David Pocock is in doubt for Sunday's test against England.
Pocock hasn't played since suffering a knee injury in the opening Bledisloe Cup game against the All Blacks in August, and he was expected to make his comeback at Twickenham this weekend.
But he's injured a calf muscle at training and is awaiting the results of a scan.
Australia were trounced 33-6 by France in the opening game of their 4-match northern tour.
