Kilmacud Crokes' third All-Ireland SFC title win is in doubt as Glen seek "clarification" on whether the Dublin club had an extra man on the pitch during the final play of the game.
Throughout the game, both teams had the lead in parts, and as the final few minutes approached, the match still hung in the balance. Kilmacud were under a lot of pressure from Glen in the closing stages, as their victory was made possible by a stunning Conor Ferris save at the very end.
However, it has seemingly come to light that the champions appeared to have an additional player on the field for the final moments of the game. And GAA pundit Joe Brolly has called for a replay of the game due to the breach of one of the game's most "fundamental" rules - each team having 15 players on the pitch.
