Offaly and Derry will meet in the Allianz League Division 3 final next weekend after the two sides agreed to play-off for the title.
Both counties won their respective semi-finals at the weekend and secured promotion.
But with Offaly due to play against Louth in the opening round of the Leinster Championship in two weeks' time, the original plan was to hold no final.
However, both counties agreed to play the game and announced it yesterday. Offaly GAA chairman Michael Duignan confirmed the agreement to RTÉ Sport.
The GAA has confirmed the match will take place at Croke Park on Saturday at 5pm.
Derry’s first outing in the Ulster SFC is against the winner of Down and Donegal on 11 July.
