All Blacks second five-eighth Ryan Crotty is the major casualty from the World Champion's 51-20 record victory over Australia.

Team doctors revealed that Crotty has been ruled out with a broken jaw, and will miss at least four weeks of rugby.

This scratches Crotty out for the All Blacks home Tests against Argentina and South Africa in the coming weeks.
