England No 8 Billy Vunipola has been ruled out for at least three months after undergoing knee surgery.
The Saracens star suffered a torn cartilage during England's 27-14 victory over Argentina at Twickenham on Saturday.
He underwent surgery on Sunday and will miss England's defence of the Six Nations crown, which begins on February 4.
The news is a big blow for England, for whom Vunipola has been outstanding in 2016, establishing himself as one of the world's best No 8s.
"Billy's been absolutely fantastic for England over the last 11 months and we wish him a quick recovery," said England head coach Eddie Jones.
"He's a very influential player in the set-up and there's no doubt he'll be missed for the game against Australia.
"But where there is an injury, there's an opportunity for someone else.
"We've had five or six frontline players missing throughout the series, so I've no doubt we'll adapt and work that little bit harder this week. I'm sure the players will respond to this by going up a level and peak for this game."
