Players involved in the tunnel brawl at half-time in the Dublin/Tyrone Allianz FL Division 1 match in Omagh on Saturday night look set to escape sanction because of inconclusive evidence.
The GAA's Central Competition Controls Committee has set up an investigation into the incident but identifying those involved clearly and getting any charge against them to stick may not be possible on the evidence available.
Video evidence from mobile phones is not admissible while the only camera angle from the broadcasters does not make it clear who was involved.
Both county boards can expect to be hit with heavy fines with a reassertion of match protocols around exiting the field at half-time.
Referee Cormac Reilly did show Tyrone's Pádraig Hamsey a black card when the teams returned for the second half for allegedly verbally abusing an opponent as the teams left the field.
Dessie Farrell described the brawl that broke out at half-time in Sunday's Division 1 defeat to Tyrone in Omagh as "needless" with the GAA's disciplinary arm now primed to examine footage of the incident.
