Linfield midfielder Jamie Mulgrew will miss Tuesday's Premiership match with Glentoran because of suspension.
Mulgrew and Crusaders skipper Colin Coates are due to be given two-match bans following their clash at the end of a league match between the clubs.
The pair got involved in a flare-up after the final whistle in Linfield's 1-0 win at Seaview on 1 April.
The suspensions start on Monday so the players will be available for the Irish Cup final on Saturday, 7 May.
Linfield said they were astounded at the outcome of the disciplinary hearing and would consider the matter at its meeting on Monday.
