Kevin Sinfield has being charged by the Rugby Football League following the first dismissal of his illustrious career last week.
The Leeds and England captain has been charged with a grade C offence after head-butting Castleford full-back Luke Dorn towards the end of a gripping 24-24 draw between the two Yorkshire teams on Thursday evening.
Rhinos coach Brian McDermott had urged for leniency, describing the incident as a "momentary" lapse in discipline, but a grade C charge carries a ban of between two to three matches.
Due to a near exemplary previous record, Sinfield may be shown some leniency at a disciplinary hearing which will be held on Tuesday.
However, anything longer than a two-game ban will see the 33-year-old miss Leeds' Challenge Cup semi-final clash with Warrington on August 9.
Elsewhere, Travis Burns and Adam Walker of Hull KR and Salford duo Josh Griffin and Tommy Lee have been charged with grade A offences for punching during the Red Devils' victory.
Lee has also been charged with making a grade B shoulder charge on Burns in the same fixture, while team-mate Matty Ashurst faces the same grade for making dangerous contact with Jason Netherton.
All six players have until 11am on Tuesday to submit an early guilty plea, but Lee may only do so for one of his offences.
