The Wallabies are monitoring goal-kicking whiz Christian Leali'ifano, who suffered a compression injury to his ankle in Australia's dazzling 54-17 defeat of Argentina on Sunday.
He left the field at half-time after he was injured while tackling Pumas winger Horacio Agulla in the 33rd minute.
He attempted to convert Adam Ashley-Cooper's 34th-minute try after getting back on his feet but missed.
The Wallabies don't believe the injury is too serious but will monitor it leading into the third Bledisloe Test against the All Blacks in Dunedin on October 19.
Wallabies captain James Horwill injured the AC joint in his right shoulder in the match.
It is also not expected to be a serious injury but will require further monitoring.
