[6] Connacht, Leinster, Munster and Ulster each organise a provincial championship.

During the All-Ireland quarter-final clash between Armagh and Monaghan, Gardaí arrested seven people and 15 fans were ejected from Croke Park after a fight broke out on Hill 16 before the penalty shoot-out.

[31] Video footage later emerged on social media showing blows being exchanged between Armagh and Monaghan fans and some of those involved being knocked to the ground.

[32] The footage was condemned by the GAA, saying it represented "unacceptable behaviour from a small number of supporters", warning fans that Hill 16 could be converted to seats if fighting in the terraced stand continued.

[33][34] Earlier in the match, the Hawk-Eye score detection system malfunctioned again after it returned a 'data unavailable' message.

[35] The GAA requested an explanation from Hawk-Eye who concluded that the message was a result of operator error.
