The Mayo county board have been hit with a €5,000 fine after missiles were thrown from the crowd at Kerry players during the recent National Football League game in Castlebar.
Kieran Donaghy, who has since received a one-match ban for reacting with an offensive gesture to the home supporters, was one of a number of Kerry players who had coins and missiles thrown in their direction.
The Mayo board have also been instructed to install CCTV cameras at McHale Park in a bid to ensure there is no repeat of the incidents.
Mayo's bid for league survival, meanwhile, suffered a further blow with the confirmation that Peadar Gardiner has been ruled out for the rest of the campaign.
The Crossmolina defender sustained a broken jaw in a club match at the weekend and faces a lengthy spell on the sidelines.
Elsewhere, Waterford will enjoy home advantage in Sunday's National Hurling League play-off against Cork after it was announced the match has been swithced from Limerick's Gaelic Grounds to Walsh Park.
The match will determine who finished second and third in the standings with the winners due to face Limerick and the losers facing Tipperary in the quarter-finals on Sunday week.
