All Blacks prop Owen Franks has been ruled out for the remainder of the rugby season due to his ongoing Achilles injury.
Franks, who had already been ruled out of the Rugby Championship, will now also miss the end-of-year tour after deciding to undergo surgery on Friday.
The All Blacks and Crusaders had been managing Franks' problem all year, but he was a late withdrawal from the second Bledisloe test after the injury became more serious.
"It's better to get it right and let him have a full recovery and a pre-season and get back for the Crusaders," Hansen said today.
The All Blacks will also be without Waisake Naholo for this weekend's clash against Argentina, with the Taranaki winger ruled out due to a concussion suffered against Counties Manukau.
