Mayo GAA have "ceased all dialogue" with millionaire benefactor Tim O'Leary after his tweet calling for the county's senior football manager James Horan to be sacked in the wake of the nine-point loss to Monaghan at the weekend.
O'Leary, who is the financier of the Mayo Supporters Foundations, tweeted "#Horanout We are not very good #TruthHurts always", two hours after the 2-16 to 0-13 defeat.
He subsequently apologised for the social media outburst on Monday, commenting, "Sorry for my outburst yesterday - had a few too many pints - lesson learned - I am going to keep my mouth shut going forward".
As of Tuesday afternoon he appears to have deleted his Twitter account but Mayo GAA have moved to cut dialogue with O'Leary, stating that the county board "will not engage with stakeholders whose behaviours deviate from what has been mandated by our clubs".
"The Mayo GAA Executive can this evening confirm that we have ceased all dialogue with Mr. Tim O'Leary," they said in a statement on Monday night.
"Although relations were strained for a number of months, a way forward was agreed in January and it was hoped that both parties would be able to work together for the betterment of Mayo GAA, this however is now not the case.
"The club delegates of Mayo GAA have mandated agreed behaviours based on mutual respect, the exclusion of animosity and the inappropriate use of communication channels such as social media.
"Mayo GAA will not engage with stakeholders whose behaviours deviate from what has been mandated by our clubs and in light of recent social media comments made by Mr. O’ Leary engagement has now ceased.
"Mayo GAA will be making no further public comment on this matter."
O'Leary had stated his support for the management as recently as last Thursday when he tweeted, "Horan is the best possible manager to get the maximum with the current group of players. A bit of luck with injuries would not go amiss".
In 2019, Mayo's county board and O'Leary had been locked in a dispute over the latter's concerns regarding governance issues.
The Mayo Supporters Foundation had also been withholding €250,000 of money it had fundraised for Mayo GAA.
