The touring Wallabies are likely to lose two of their leading backs, casualties of their battling win over Italy at the weekend.
Coach Robbie Deans fears the worst after midfield generals Berrick Barnes and Timana Tahu suffered probably tour-ending knee and hamstring injuries, which they'll have scanned when they arrive in London.
Deans says they'll probably soldier on with a squad of 32 if Barnes and Tahu both go home.
The Wallabies play England this weekend.
