Hull KR say they will contest the two-match ban captain Elliot Minchella has been given.
As it stands he will miss their final regular game of the season, against Leeds on Friday, and their first play-off tie.
The match review panel charged the forward with a Grade C head contact offence after he was sin-binned for a high tackle on Matt Moylan in the win over Leigh on Friday.
Going into the final round of games the Robins are in second place and victory over the Rhinos will see them straight through to the play-off semi-finals.
Meanwhile, Catalans Dragons centre Arthur Romano has been given a one-match ban for a Grade B head contact in their win over London Broncos.
Les Dracs face Hull FC in their final game of the season on Saturday and a win would be enough to see them claim the final play-off spot if Leeds do not beat Hull KR and Leigh lose at St Helens.
