The redevelopment of Casement Park will include a capacity considerably below 34,500, the Irish Examiner are reporting.
At an Ulster Council meeting earlier this week, it emerged that a scaled-down version of the venue is more likely to be built.
The Examiner are reporting 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 said that it would be suitable for Antrim league and championship matches, as well as Ulster senior football semi-finals.
While the Irish Government's £43 million (€50m) pledge remains in place, the Irish Examiner reporting that the £50 million (€58.5m) promised by the British government may not be drawn down for several reasons.
One factor is the funding pressure currently facing the UK, with the possibility that London may be forced to renege on its announcement from 12 months ago.
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.
