Moody has started all seven of the All Blacks' Test matches at loosehead prop this year, but that run will come to an end after he picked up a shoulder injury in Saturday's Rugby Championship win over Argentina.

In a less than convincing performance, the world champions won 39-22, maintaining their 100 per cent record in the tournament and moving back to the top of the table after South Africa could only draw 23-23 with Australia.

Hansen revealed after the match that Moody, who played the entire Test, is set to miss the remainder of the year after dislocating his shoulder.

"He's off to get an X-ray and it looks like he'll probably have to have an operation," he said. "It'll be the end of him for the year, I'd say."

Moody's injury adds to the problems for Hansen, who was already without tighthead prop Owen Franks after he went under the knife on Friday to repair a chronic Achilles' tendon problem.

The All Blacks' next match is against the Springboks next Saturday.
