The seriousness of the injury is not yet known and the 22-year-old is likely to be given maximum time to come right given the paucity of experienced locks in the side.
If Retallick is ruled out, Hurricanes player Jeremy Thrush will be promoted from the bench to make his test debut. The bigger problem will be with replacing Thrush as Luke Romano and Romano are the only fit locks in the squad.
All Blacks coach Steve Hansen confirmed earlier in the day that Sam Whitelock is on track to be fit for next week after breaking his finger while playing for the Crusaders. It's possible he could be risked but a more likely option is Steven Luatua coming on to the bench.
Loose forward Luatua, in the All Blacks environment for the first time, has extensive experience at lock despite having played all this season at blindside for the Blues.
