Breffni Park was chosen to host the 2006 Division Two Final of the Allianz National League between Donegal and Louth. There was controversy when Donegal's manager Brian McIver was upset as he thought the game should have been played at Croke Park in Dublin. McIver said: "It defies logic and I think the sponsors might have something to say about it as well. It's very strange that the finals can suddenly be moved from Croke Park. [...] The National League is the second biggest competition in the GAA and the finals should be staged at Croke Park". The GAA claimed it was due to "the geographic considerations in respect of the four Division One semi-finalists". Donegal's semi-final defeat of Westmeath had also taken place at Breffni Park.
