Glentoran midfielder Mark Clarke could face further disciplinary action from his club or the Irish Football Association after posting a controversial comment on his Facebook page while referring to Linfield ace Jamie Mulgrew.
Clarke was sent off near the end of the Boxing Day clash with the Blues at The Oval after referee Raymond Crangle felt he aimed a headbutt at Mulgrew.
Glens boss Eddie Patterson said after the 2-1 defeat that Clarke would be "dealt with internally" but now The Oval supremo may have to take further action against the former Cliftonville player.
Clarke signed a one-year extension to his Glentoran contract last summer but there may now be a question mark hanging over his future at the club given his disciplinary record and the controversial Facebook comment.
The player's comment was picked up by Irish League fans and attracted widespread criticism online.
Clarke's dismissal was the second time this year he has been sent off against the Blues.
Patterson said afterwards: "There were a few niggly off the ball incidents but we will deal with Mark internally from a disciplinary point of view. The bait was there and he took it.
"But I'm disappointed the referee didn't deal with the incident in the same manner for both sides.
"Mark Haughey caught Stephen McAlorum late and there wasn't a card so that was disappointing. Wee things like that annoyed us and I felt there could have been more cards shown. Blatant yellows are blatant yellows and they should be shown."
* Ballymena United keeper Stuart Addis has been ruled out for the rest of the season with a fractured finger.
Addis played 85 minutes of the derby clash against Coleraine with the injury but now he must undergo surgery.
