All GAA matches have been called off with immediate effect but training will continue, it has been announced.
A statement said that all club games will be suspended until further notice.
“The decision has been taken in the interest of public safety following a number of incidents that have been brought to our attention in recent days.
“In particular, post-match celebrations and a lack of social distancing at certain events have proved disappointing and problematic.
“This directive applies to all ages and all grades across the island.”
Social clubs and bars will also close but training will continue as per the guidelines outlined for the relevant levels in the Government’s National Framework for Living with Covid-19.
The announcement comes following videos were shared on social media of large crowds celebrating Blackrock’s county championship.
