The Wallabies have suffered more injury concerns, with versatile forwards Hugh McMeniman and Peter Kimlin ruled out of the Bledisloe Cup clash with the All Blacks in Hong Kong in a fortnight.
Both players are also likely to miss the opening Test of the European Spring Tour against Italy after McMeniman rolled his ankle at training and Kimlin strained his quad.
Their absence further stretches the Wallabies' forward depth, with key second rowers Dan Vickerman and James Horwill and flanker Rocky Elsom already unavailable for the six-match tour.
Winger Lote Tuqiri, half-back Luke Burgess and back rower Wycliff Palu have yet to prove their fitness ahead of the tour following stints on the sidelines.
