The All Blacks suffered a double blow on the eve of Saturday's Test against the Wallabies with captain Richie McCaw and wing Cory Jane ruled out after picking up injuries in training.

"Richie McCaw has been ruled out of Test with tight calf. Cory Jane also out w mild hamstring strain," the All Blacks posted on their Twitter account.

A team spokesman would not comment on the posting but said injury updates would be made at the captain's run later Friday. It is understood the injuries flared up during training on Thursday.

Sam Cane replaces McCaw on the openside flank and Charles Piutau will start on the right wing, with Steven Luatua added to the replacements, the All Blacks' official Twitter account said.

In recent weeks McCaw has been troubled by a knee injury suffered against Argentina early in the rugby championship.

Jane had been rushed back after only two appearances in New Zealand's provincial competition since sitting out most of the year with knee ligaments damaged in pre-season training.
