Woodvale have decided not to play in the Ulster Shield T20 finals day and will be replaced by Holywood.
The Ballygomartin side informed the NCU last week that there is no appetite within the club to travel to the NW to take part in the finals day.
St Johnston, winners of the Eric Cooke Cup will now take on Holywood at the Boathole on Sunday (11.30), with NCU T20 Shield winners Armagh taking on Strabane at the County Tyrone venue at 12 o'clock.
The final will be held following that game starting around 4-4.30pm.
Also this Sunday, the Ulster Cup T20 finals day takes place in the NCU area, with North Down playing Bready at Comber (11.30), while Waringstown face Coleraine at Saintfield (11am).
The final will take place at The Green, Comber starting at 4pm approx.
The T20 days are being held as a compromise after the competitions were being phased out, with the NW citing fixture congestion.
