Injured flanker David Pocock is again missing from Australia's starting lineup for its Rugby World Cup pool C match against the United States on Friday.
Pocock was a late withdrawal from the Wallabies side to play Ireland last Saturday with a back injury and his absence was sorely missed by the Tri-Nations champions, who were dominated at the breakdown as Ireland won the match 15-6.
No 8 Ben McCalman will again deputise for Pocock as coach Robbie Deans gives a number of untried squad members a chance to impress against the US Eagles.
Captain James Horwill has been rested for the match, with halfback Will Genia to lead the side.
Veteran lock Nathan Sharpe replaces Horwill in the second row, one of seven changes from the side that started against Ireland.
