Salford are facing possible repercussions from the RFL for fielding 14 players during a crucial period of their 34-30 Super League victory over Castleford on Saturday.
Brian Noble: New Salford coach
The Tigers noticed the discrepancy and have lodged a complaint with the RFL, who are expected to make a statement over the matter on Wednesday.
Castleford chief executive Steve Gill has claimed three plays took place while the Reds had an extra man on the field of play after making a substitution four minutes from time.
Salford went on to secure the victory that took them off the foot of the table in Brian Noble's first match in charge since take over at the Salford City Stadium.
There is no precedent that would see Cas awarded the points from the contest but the Reds may face a fine or a points deduction if the RFL rules they are in breach of its operational rules.
