Hull KR centre Kris Welham has been charged with a grade A offence of head-butting Castleford full-back Luke Dorn.
The incident occurred during last week's 30-10 First Utility Super League home defeat to the Tigers, who are joint top of the league with three straight victories.
Welham, who was charged by the Rugby Football League's match-review panel, has until 11.00am on Tuesday to submit an early guilty plea.
The panel also issued cautions to Castleford scrum-half Liam Finn for dangerous play in the same match, which earned him a spell in the sin bin, and Warrington's England forward Ben Westwood for a dangerous tackle during his side's 18-16 win over Hull FC on Sunday.
Are St Helens the real deal this season?
