The Gaelic Players' Association's CEO Paul Flynn has called on inter-county managers and players to adhere to the two-week ban on collective training.
All GAA activity has suspended for gaelic football, hurling, ladies football and camogie until March 29th.
Flynn says "strict coherence" is expected from all inter-county squads and that their insurance would be void if they breach the directive.
The GPA and GAA have agreed that all collective training, collective gym sessions and collective team meetings are strictly prohibited throughout the period," he said in a statement.
"Strict coherence is expected from all squads. Please be advised that there will be no insurance cover for players if breaches of this directive take place, nor will any expenses be paid.
"It is essential that we show leadership and play our role in this and hold ourselves accountable for our actions for the betterment of our communities. We have an opportunity to help protect vulnerable members in our communities who are at significant risk.
"We understand the move to postpone the games will raise questions for many of you, however, at this point your health and safety, that of GAA supporters and that of the wider community has to be the number priority.
"If you or one of your team-mates were to become infected, the whole squad would need to self-isolate for at least two weeks."
