GAA President Larry McCarthy says the association will investigate reports of overcrowding at Sunday's Tailteann Cup semi-finals.
A number of fans took to social media on Sunday to complain about congestion issues inside Croke Park as Meath defeated Antrim and Down beat Laois.
One wrote: "Fantastic opportunity to support @OfficialDownGAA today, but what unfolded between the 2 games was a logistical failure from @officialgaa No reserved seating, 3/4 stadium empty but 4 counties squeezed into the Lower Hogan was mayhem and quite frankly scary!!! A disgrace!!!"
