The All Blacks' 33 -10 victory over Wales at Cardiff has been overshadowed by a high hit by Andrew Hore.
The New Zealand hooker is likely to be cited after putting in a high tackle on Welsh forward Bradley Davies in the second minute of the match at Millennium Stadium in Cardiff.
Davies appeared to be knocked unconscious after being hit from behind by Hore's swinging arm and was later taken to hospital.
Wales coach Warren Gatland says he is leaving the issue to the citing commissioner, but says people will be able to draw their own conclusions.
"Doesn't look the best in the world - looks like he's just been caught from behind.
"You don't usually associate the All Blacks as a side that resorts to cheap shots and I hope it's not the case. I hope it's just an accident."
All Blacks' coach Steve Hansen says he didn't have a clear view of Hore's hit, but agrees he is likely to be cited.
"It's unfortunate that it's happened, and no doubt there'll be more to be talked about."
Hansen says they may have to call in a replacement if Hore is suspended, as fellow hooker Keven Mealamu remains under an injury cloud, leaving rookie Dane Coles as the only fit rake in the squad.
The New Zealanders led 23-0 at half time with tries to Liam Messam and Tony Woodcock, both converted by Aaron Cruden.
In the second half, Luke Romano scored again for the All Blacks before Wales got one back through centre Scott Williams. Alex Cuthbert scored another try for Wales.
Cruden, a late substitute for Dan Carter who withdrew with a leg injury, kicked four penalties and three conversions for a total of 18 points.
The win extended the All Blacks' unbeaten run to 20 while European champions Wales have now lost six matches in a row.
Captain Richie McCaw was named man of the match.
