Berrick Barnes and Adam Ashley-Cooper will take no further part in the Rugby Championship due to injuries sustained in Australia’s recent loss to South Africa.
Barnes suffered a punctured lung while Ashley-Cooper was taken to hospital following a heavy head knock. It was later confirmed that Ashley-Cooper had suffered a concussion, and he along with Barnes will travel home to Australia.
There is also doubt over winger Digby Ioane (knee), No 8 Radike Samo (shoulder) and hooker Tatafu Polota-Nau (neck/shoulder).
The Wallabies have called up lock Cadeyrn Neville and back Luke Morahan as cover for their final Rugby Championship Test against Argentina.
