All Blacks' hooker Andrew Hore has been cited for allegedly striking Wales lock Bradley Davies in the at Millennium Stadium in Cardiff.
Hore appeared to hit Davies with a swinging arm from behind in the opening couple of minutes of the All Blacks' 33-10 win on Saturday.
Davies was knocked out and was later taken to a hospital.
The New Zealand hooker was cited Sunday by the Six Nations Committee, which oversees disciplinary matters in the autumn internationals in the northern hemisphere.
The date of the hearing before an International Rugby Board judicial officer has yet to be set.
