Dean Greyling of South Africa has been cited for foul play during the Springboks's 21-11 loss to New Zealand in Dunedin on Saturday.
Greyling is alleged to have contravened Law 10.4 (a): Punching or Striking.
He made contact with New Zealand captain Ritchie McCaw with his arm in the 64th minute of the Rugby Championship match.
The referee for the match; 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 judicial officer Paul Tully.
