Saints centre Mark Percival will miss the club’s game with Huddersfield after accepting a one-match ban.
Percival was sin-binned for disputing a decision in the club’s defeat to Wakefield on Sunday, and was charged off the back of it.
Saints have accepted the penalty notice and he will now sit out the club’s match against struggling Huddersfield on Friday.
The 23-year-old has been in fine form so far this season, scoring 12 tries in 11 appearances.
