New Zealand fly-half Dan Carter will miss his team's final Pool C match because of a calf strain.
Luke McAlister will move off the bench to cover for Carter while wing Doug Howlett steps in to the replacements for Saturday's match against Romania in Toulouse.
Carter felt tightness in his left calf following Thursday's training and, after consulting the All Blacks medical team this morning, withdrew from the line-up.
The team said his availability for the All Blacks' quarter-final would be re-assessed early next week.
'Luke is an experienced first-five (fly-half) at test level. This will add to our options at the position while we take a sensible approach to Dan's calf strain,' said All Blacks coach Graham Henry.
'Our goal through the pool round is to give game time to as many of our 30-man squad as possible. Dan has played two matches already so this has a pretty minor effect on our strategy.'
Henry noted that Nick Evans, the team's other option at fly-half, remains at full-back to give Mils Muliaina (hamstring) and Leon MacDonald (bruised thigh) additional time to recover from earlier injuries.
The All Blacks have already secured their place in the quarter-finals as winners of Pool C. They will meet either France, Argentina or Ireland in Cardiff on 6 October.
