London Irish scrum-half Tomas O'Leary faces an RFU disciplinary hearing following his red card in Saturday's Premiership game at London Wasps.
He was sent off for allegedly stamping on Wasps flanker James Haskell's head.
Another player to face a disciplinary panel is Worcester number eight Jonathan Thomas. He was shown a red card on Saturday for allegedly striking Northampton's Sam Dickinson.
O'Leary's case will be heard on Tuesday, with Thomas's on Wednesday.
