BRIAN O'DRISCOLL will miss Leinster's Amlin Challenge Cup quarter-final against Wasps after he received a three-week ban for stamping on Italy's Simone Favaro in Saturday's Six Nations defeat.
The IRFU will wait until they have received the written judgment before deciding whether to appeal.
Former captain O'Driscoll admitted that he had committed an act of foul play, but argued that it had not warranted more than the yellow card that referee Wayne Barnes produced at the Stadio Olimpico.
The 34-year-old was accompanied to the hearing by Ireland coach Declan Kidney, manager Mick Kearney and solicitor Donal Spring, but the three-man disciplinary committee ruled that the stamp was contrary to Law 10.4(b) and issued the three-week ban, which will expire on April 8, three days after Leinster's Adams Park clash.
Indeed, although the offence was considered to be mid-range, O'Driscoll could have faced a five-week ban but for his previous clean disciplinary record.
Having successfully appealed the length of prop Cian Healy's ban for a similar offence during the Six Nations on the basis that their decision to extend a three-week suspension over four weeks was not permissible, the IRFU will be reading the judgment carefully before making their decision.
