Garry Ringrose will learn on Thursday if he is able to play any further part in Ireland's Guinness Six Nations title bid after being sent off against Wales.
Ringrose will appear before an independent disciplinary hearing after receiving a 20-minute red card, upgraded from yellow by the bunker review system, for a dangerous tackle on centre Ben Thomas in the round three fixture.
Ireland host France in a pivotal title clash in Dublin on 8 March before closing their Championship against Italy on the final weekend, with Ringrose in danger of missing both games.
The length of ban will be two to six matches depending on severity of the incident with reductions available for previous clean records - which Ringrose has - and for attending tackle school.
