Wallabies scrumhalf Will Genia has been ruled out of rugby for six months due to a ruptured ACL in his knee.
Genia was on crutches following Saturday’s Test against the Springboks, and a subsequent trip to the hospital for scans and tests confirmed that he won’t play again in 2012.
Nick Phipps is expected to start in Genia’s place against Argentina next week, while Brett Sheehan will join the squad as scrumhalf cover.
Genia is the third senior Wallabies player to be sidelined in recent months. James Horwill (hamstring) and David Pocock (knee) are unavailable for the Rugby Championship because of serious injuries.
Lock Sitaleki Timani also picked up a hamstring injury on Saturday and is unlikely to play Argentina next week.
The good news is that versatile back James O’Connor will make his return to the squad in the next week. O’Connor is expected to play in the Test against the Boks in Pretoria.
