Ulster hooker Rob Herring is in danger of missing Friday's Pro12 semi-final against Glasgow after being cited for allegedly stamping on an opponent.
The incident took place during the defeat away to the same opponents last Saturday and, if found guilty, Herring could receive a two-match suspension.
The South African-born player will appear before a disciplinary panel in Cardiff on Wednesday.
Herring, 25, played the full 80 minutes of the match at Scotstoun.
Glasgow finished top of the Pro12 standings, earning home advantage for Friday's play-off tie.
Munster host the Ospreys in the other semi-final on Saturday, with the final taking place at Kingspan Stadium, Belfast, on 30 May.
