Dundalk goalkeeper George Shelvey has received a 10-match ban following a red card after their defeat to Drogheda United on Monday.
Shelvey was dismissed after the full-time whistle after becoming involved in an incident with officials in Weavers Park.
An Independent Disciplinary Committee of the FAI has sanctioned the former Nottingham Forest goalkeeper "for a breach of regulations on racism/discrimination" in "abuse towards a match official".
The ban is one of the longest in League of Ireland history.
A statement issued by the FAI this afternoon read: "The FAI and League of Ireland maintain a strict zero tolerance approach towards such offences and are committed to ensuring that League of Ireland matches remain a safe and welcoming environment for everyone.
"In accordance with FIFA regulations and the FAI disciplinary regulations, George Shelvey will serve a ten-match suspension.
"Please note the decision of the Independent Disciplinary Committee may be appealed."
Dundalk have confirmed they will not be appealing and will help educate Shelvey on the incident.
They said: "George attended today's Independent Disciplinary Control Unit hearing in which he explained that he deeply regrets the language that he used towards the referee.
"While George realised very quickly that he had used inappropriate language, he did not, at first, comprehend the discriminatory aspect of his words.
"However, having discussed the matter with club officials he now fully accepts that his words were not only offensive, but also discriminatory.
"Both George, and the club, accept the sanction imposed by the Independent Disciplinary Control Unit and will not be making an appeal.
"Going forward, Dundalk FC will work with George to develop his understanding of these issues."
Shelvey will not be able to play until Dundalk's fixture away to Bohemians on 26 July as the fixture list stands.
