Dublin Senior Football manager Dessie Farrell has been suspended for 12 weeks after some footballers broke coronavirus restrictions to train on Wednesday.
Several members of the six-in-a-row All-Ireland champion’s squad took part in a secret dawn training session on Wednesday morning.
It was believed to have been a non-contact session at Innisfails GAA club in Balgriffin.
However in a statement on Thursday, Dublin GAA said that - following an investigation - there "was a breach of COVID-19 guidelines".
"The County Management Committee have suspended Dublin Senior Football manager Dessie Farrell for 12 weeks with immediate effect", it said.
The statement added that management and players "recognise that this was a serious error of judgement and apologise unreservedly for their actions."
The session came just a day after the GAA warned senior county teams that any pre-mature return to training could put the return to play "in serious jeopardy."
Senior players will officially be permitted to return to training on April 19th, under the latest Government roadmap announced on Tuesday.
In a letter to county and club secretaries just hours after the announcement, the GAA noted that the return was, "conditional and will very much depend on what happens in terms of the overall Covid-19 picture in the coming weeks."
"For that reason, it is more important than ever that no collective training sessions are held between now and the Government indicated return dates,” it said.
"Breaches in this context will not only be dealt with under our own rules but would likely put the broader plan to return to activity in serious jeopardy."
