Munster's James Cronin has been cited for a second-half stamping incident in his side's PRO12 defeat to Leinster on Saturday.
Leinster ran out 25-14 winners at the Aviva Stadium but there could be more misery for Munster as Cronin has been cited for stamping on scrumhalf Jamison Gibson-Park.
With Munster camped on the Leinster line on 73 minutes, Cronin appeared to stamp down on the prone Gibson-Park with his boot making contact with the Leinster man's face.
A statement from the league confirmed: "James Cronin, front row (No 17), for Munster Rugby has been cited by the Citing Commissioner in charge for alleged foul play in the 73rd minute against a Leinster player under Law 10.4 (b) – Stamping on an Opponent.
"A disciplinary hearing will be held in Glasgow on Wednesday, October 12, 2016."
