Matty Lees has been handed a two-game penalty notice following Thursday's win over Salford.
The prop was sent off after an incident with Niall Evalds in the 37th minute of the match.
The Match Panel consider the incident to be a Grade C offence (High tackle – reckless – tried to tackle but reckless about outcome) – and that carries a two to three match suspension.
Saints have accepted the notice.
