Brian O'Driscoll has been cited for an alleged stamp during Ireland's Six Nations defeat to Italy on Saturday.
The veteran centre has been summoned to a disciplinary hearing after he was sent to the sin-bin on the half-hour mark for an apparent stamp on Simone Favaro.
O'Driscoll lifted his right leg and brought it down on to the chest of the Italy openside, who was lying on the wrong side of the ruck and yelled out in pain after feeling the force of O'Driscoll's foot.
The 34-year-old has been reported by independent citing commissioner Aurwel Morgan over the incident in what is expected to be his last appearance for Ireland.
A statement issued by the Six Nations read: "Brian O'Driscoll, the Ireland centre, has been cited by the independent citing commissioner for an alleged stamping or trampling on an opponent, contrary to Law 10.4 (b), in the RBS 6 Nations match between Italy and Ireland on Saturday 16th March 2013. Details of the Hearing will be announced later."
The recommended suspension for a low end stamping offence is two weeks, the mid range five weeks and top end nine weeks, up to a maximum of one year.
O'Driscoll, who has won 125 caps, has insisted he has yet to make a decision on his international future, although it is widely anticipated that he will retire following this summer's Lions tour.
Ireland coach Declan Kidney, whose own future is under severe scrutiny, believes O'Driscoll is capable of continuing at the top level.
"Brian has had a strong Six Nations. He was outstanding against Wales and had a good match against France. I thought he did well against Italy too," Kidney said.
"He's earned the space and time to be able to make up his own mind. Players are the only ones who know when the time is right to go."
