Leroy Houston could emerge as the latest Wallaby after Sean McMahon has been ruled out of next weekend's Rugby Championship clash with Argentina.
McMahon was sent home after suffering an ankle injury in the 18‑10 defeat to South Africa.
The 22‑year‑old had scans after the game and the early diagnosis is a high ankle sprain, which could sideline him for up to a month.
The injury will send coach Michael Cheika back to the drawing board for another solution at No.8, with McMahon having been brought in to replace David Pocock.
Test newcomer Lopeti Timani is the only recognised cover for that position in the current squad and he could make his starting debut in the clash with Argentina.
The Wallabies will meet Argentina at 6.30am this Sunday.
