All Blacks star Dan Carter has been cited for an alleged dangerous tackle on Wales scrum-half Martin Roberts during Saturday's Test match at the Millennium Stadium.

Carter will face a disciplinary hearing in Milan on Monday, where the New Zealand squad has arrived to prepare for next weekend's clash against Italy.

He is due to appear before International Rugby Board-appointed judicial officer Jeff Blackett, who is also the Rugby Football Union's disciplinary chief.

Carter, who was not yellow-carded for the offence by match referee Craig Joubert, could receive a minimum one-week ban.

Anything more than that would put his participation against England at Twickenham on November 21 in grave doubt.

Carter, capped 64 times, kicked 14 points during the All Blacks' 19-12 victory. He was cited by Australian match commissioner Scott Nowland, who had until Monday evening to make a decision.

Carter is the third All Blacks player to be cited in a week, following one-week suspensions dished out to wing Sitiveni Sivivatu and prop Tony Woodcock for foul play during the victory over Australia in Tokyo.
