All Blacks fly-half Dan Carter has been forced to pull out of Saturday's Test against Argentina after suffering a calf strain.
The ace playmaker was withdrawn from the side just hours after the team was announced on Thursday.
Coach Steve Hansen said Carter had been carrying a tight left calf in training during the week but had hoped to play.
"However, at training this morning it was apparent that he would not be able to play so we have done the sensible thing and withdrawn him from the Test match," Hansen said.
Aaron Cruden will now start in the 10 jersey, with Beauden Barrett, who made his Test debut against Ireland in June, called on to the bench.
It will be the 23-year-old Cruden's 13th Test but just his fifth start as he continues to benefit from injuries.
He was called up during last year's World Cup when Carter was injured and came on against Argentina in the quarter-finals when then fly-half understudy Colin Slade was injured.
