The Antrim County Board last night voted against giving Central Council the power to open up Croke Park to other sports on another big night in the Rule 42 debate.
Antrim delegates voted 52-34 against allowing the GAA's headquarters to host Irish rugby and soccer international games.
Eight of the Ulster counties are now in opposition to changing Rule 42, with Armagh expected to follow suit in advance of Saturday's vote at Congress in Dublin.
However, in other parts of the country the mood is generally much different. And last night three more counties threw their weight behind the calls for change.
In Leinster, Kilkenny and Louth (37-9) came out in support of opening Croke Park while Lansdowne Road is under redevelopment. All 12 Leinster counties back change.
Meanwhile, in Connacht, Leitrim voted in favour of change on a temporary basis with a landslide 59-3 result. Mayo have opted not to issue a mandate to their delegates, who will have to make up their own minds at Congress. The remaming western counties are in favour of an amendment.
Tonight, there will a big focus on Limerick and Cork county board meetings. Cork are expected to support a 'No' vote, however, Limerick are thought to support change, leaving the Rebels as the only dissenting voice in Munster.
However, despite most counties supporting the motion for change, doubts remain whether this will translate into the two-thirds majority needed to pass any motion due to the secret ballot used at Congress.
Proponents of change fear that delegates who don't agree with their county board's instructions will ignore mandates on the day.
