Springbok prop Dean Greyling has been cited for alleged foul play during Saturday's 21-11 loss to the All Blacks in Dunedin.
Greyling is alleged to have contravened Law 10.4 (a) punching or striking, when he made contact with New Zealand captain Ritchie McCaw with his arm in the 64th minute of the match.
Referee George Clancy issued a yellow card for the incident. Upon further review of the match footage the citing commissioner deemed in his opinion the incident had met the red card threshold for foul play.
The citing is to be considered in the first instance by SANZAR Duty judicial officer Paul Tully.
