The All Blacks have beaten Wales 33-10 in their penultimate test of the season at Cardiff's Millennium Stadium - but a high tackle from New Zealand hooker Andrew Hore could overshadow the win.
Hore is certain to be cited after his swinging arm from behind on Welsh forward Bradley Davies in just the second minute.
Davies appeared to be knocked unconscious after being hit from behind by Hore's swinging arm, and the lock was taken to hospital.
Davies became the first of three Welsh players to leave the field with injury in just the first quarter of the match.
The All Blacks coach Steve Hansen says they may have to call in a replacement if Hore is suspended, as fellow hooker Keven Mealamu remains under an injury cloud.
That leaves rookie Dane Coles as the only fit rake in the squad.
The New Zealanders scored three tries to Wales' two and led 23-0 at half-time, with Liam Messam and Tony Woodcock crossing the chalk.
Then Luke Romano scored again before Wales got one back through centre Scott Williams.
Aaron Cruden kicked four penalties and three conversions for the All Blacks for his personal haul of 18 points.
Captain Richie McCaw was named man of the match.
