Brian O'Driscoll will discover on Wednesday the extent of his punishment for stamping on Italy's Simone Favaro.
The Ireland centre was sent to the sin bin during his side's 22-15 Six Nations defeat in Rome on what was possibly his final appearance for his country.
And a disciplinary committee comprising Robert Williams, Mike Hamlin and John Doubleday will hear the case in London on Wednesday morning.
Stamping offences can carry suspensions of between two weeks and a year depending on their severity.
O'Driscoll's previous good record - Saturday's incident was just his second sin-binning - is likely to count in his favour.
