Danny Grewcock has been cited for an alleged punch in Bath's defeat by Clermont Auvergne in Saturday's European Challenge Cup final.
Grewcock has a poor disciplinary record
The 34-year-old is accused of hitting Clermont's Thibault Privat during the second half of Bath's 22-16 defeat.
Privat is reported to have sustained a broken nose during the match.
If found guilty, Grewcock could face a lengthy ban because of his poor disciplinary record which includes being sent off for England in 1998.
He was also banned for two months for biting All Blacks hooker Kevin Mealamu while playing for the Lions.
Grewcock, who has won 69 England caps, was cited by the Italian match commissioner Achille Reali but a date for the hearing has not yet been set.
