Munster beat Ulster by a point on Friday night with any gamblers cursing Ian Humphreys' late conversion miss which would've won the game for his side.
In the 41st minute of the game, there was incident involving Donncha O'Callaghan and Stuart Olding. The Munster second row has been cited for allegedly kicking Olding in the head.
The Ulster back had to leave the pitch for a head injury assessment following the incident.
O'Callaghan will appear before a disciplinary committee later this week.
