Local Minister Heather Humphreys says "Clones is the place for the Ulster Final", despite concerns that it could be moved to a redeveloped Casement Park.
Plans to redevelop Belfast's Casement Park have faced lengthy delays, but Ulster GAA says it remains a priority.
There are fears in Clones that revamped Casement could become the new home of the Ulster Final once works are complete.
Speaking as a recent Shared Island Dialogue event in Drumhowan, Co Monaghan, Minister Humphreys said Clones creates a "fantastic buzz" on Ulster Final day, and added that she sees "great potential for Clones".
Minister Humphreys told Northern Sound that she will "explore all opportunities to get money to further upgrade St Tiernach's Park":
Meanwhile, the Ulster Final returns to St Tiernach's Park for the first time since the pandemic.
People are advised to expect traffic disruption around Clones, as this afternoon's final between Derry and Donegal is a sell-out crowd of around 29,000.
