New Zealand captain Richie McCaw will miss out on his 100th All Blacks cap this weekend, as he sits out his side's Pool A match against underdogs Japan with a minor calf strain.
The veteran flanker joins fly-half Dan Carter and Mils Muliaina on the sidelines for a match that the hosts would still expect to win comfortably.
In McCaw's absence, hooker Keven Mealamu will lead the team on Friday morning.
