Casement Park is set to have a capacity below 34,500 as anticipated.
The Irish Examiner report; at an Ulster Council meeting earlier this week, it emerged that a scaled-down version of the Belfast venue is now likely.
The stadium will still be regarded as a provincial ground; but it is expected to be reduced to about half the original size, if not smaller.
It would be suitable for Antrim league and championship matches, as well as Ulster senior football semi-finals.
While, disappointing news, it clears the way for St. Tiernach's Park, Clones to continue to host the Ulster senior final.
Clones, currently holds a maximum of 29,000 to 30,000. This number is believed to be well above the new planned size of the stadium
While the Irish Government’s £43 million (€50m) pledge remains in place. The Irish Examiner understands the £50 million (€58.5m) promised by the British government may not be drawn down for several reasons.
Funding pressure facing the UK government, is believed to one of the factors. There is also reluctance within the GAA, as it is understood that a condition of the funding would give the British government a place on the deeds of the new stadium.
A new sub-committee comprising GAA president-elect Derek Kent, Munster chairman Tim Murphy, trustee John Murphy and Britain GAA chairman Seán Hopkins has been tasked with assessing the project’s viability.
Demolition work has been completed. Piling has taken place to ensure the five-year planning permission, which is due to lapse next month, remains valid.
