The Wallabies have suffered their third major setback within a week after Quade Cooper suffered a suspected ruptured Achilles.

Cooper picked up the injury during the 41-26 victory over Argentina yesterday.

He joins superstar Samu Kerevi, who has been ruled out for the rest of the year with a knee injury.

This comes as captain Michael Hooper was a late withdrawal due to personal reasons, with no timeframe put on his return.

Australia will face Argentina at 7.10am Sunday while the All Blacks face South Africa at 3.05am Sunday.
