Australia lock Nathan Sharpe has been ruled out of Saturday's second Test against France after injuring himself at training.
Sharpe strained his groin when he stumbled during training and was forced to withdraw from the match.
'It's unfortunate but the injury is restricting Nathan, so the choice was made for us,' Australia coach Robbie Deans said.
'We gave it as much time as we could, to allow it to settle but with the game just two days away, we had to make the call and move on.'
Deans said reserve lock Dean Mumm would replace Sharpe in the starting lineup alongside James Horwill, while Queensland flanker Hugh McMeniman had been added to the bench.
'The loss of Nathan obviously tests our depth, in terms of the Test experience our two locks have but we've got total confidence in the guys who are there,' Deans added.
'They've done the work on the training paddock and competed well in their test careers so far. There's a great opportunity ahead for both of them.'
