Australia have the potential to cause yet another Rugby World Cup surprise later this year in Japan, according to former New Zealand captain Richie McCaw.

All Blacks coach Steve Hansen has included two uncapped players but made no selection surprises in his squad for this season’s Rugby Championship.

Captain Sam Warburton is willing to tell British and Irish Lions head coach Warren Gatland he is not ready to play a Test match if he has not built up sufficient game time to operate to the best of his ability against the All Blacks.

The British and Irish Lions will welcome back tour captain Sam Warburton from injury on Tuesday when they take on the Highlanders in Dunedin.
