Tonight's McKenna Cup clash between Cavan and St Mary's has been switched to the Kingspan Breffni 3G pitch.
The Section B opening round tie was due to be played on the main pitch but will now take place on the all-weather facility at the county grounds.
Meanwhile, in Section C, the Donegal-Queen's fixture will go ahead as planned in Ballybofey following two early pitch inspections.
Throw-in for both games is at 8pm.
