Glentoran goalkeeper and former Republic of Ireland underage international Aaron McCarey was sent off after hitting his team-mate during the Glens' Irish Premiership clash with Coleraine on Saturday.
McCarey reacted with fury after Cathair Friel's 80th-minute equaliser in the 2-2 draw, running straight towards Bobby Burns and appearing to strike the defender in the face before grabbing him by the shirt while he was grounded.
Burns had been tackled on the halfway line, which started the Coleraine move that led to the goal.
Glentoran had fought back from a goal down to lead but were left to settle for a draw as they ended the game with 10 men following the Monaghan man's dismissal.
Glentoran boss Mick McDermott said in an interview on his club’s YouTube account: "Aaron’s held his hands up in the dressing room and said it shouldn’t have happened.
"It was a really poor goal to concede, especially when we worked so hard to get back from 1-0 down. We were in control of the game at that moment and we didn’t get the three points."
