Video footage has emerged showing Armagh and Monaghan fans fighting during Saturday's All-Ireland quarter-final clash.
Monaghan defeated their Ulster rivals on penalties after the sides couldn't be split after more than 90 minutes of football at Croke Park.
But tempers boiled over on Hill 16 as fans from both sides exchanged blows during the last eight encounter.

A video being shared on social media shows men throwing punches and pushing each other, with those involved ranging in age from their 20s to slightly older.
Women and children also witnessed the carnage during the match, which ended 9-8 on penalties in Monaghan's favour, with Rory Beggan emerging as the Farney's hero during the spot-kicks.
Beggan twice saved from Callum Cumiskey, once in the regular round of penalties and then in sudden death.
It was a dramatic ending to a game that started at 6pm and only ended at 8.40pm with the Ulster rivals level 14 times across the 90 or so minute epic.
Having hit late, late scores to rescue results against Tyrone, Derry and Kildare already in the Championship, it was yet another last gasp success for Monaghan.
Conor McManus scored four crucial points and converted two penalties while Jack McCarron, Kieran Hughes, Michael Bannigan and Gary Mohan also scored from the spot for Monaghan.
It was further penalty agony for Armagh, having lost at the same stage, in the same way, in 2022 while they also lost this year's Ulster final on penalties.
