The inclement weather has forced the GAA's Leinster Council to move two of the fixtures in this weekend's opening round of the O'Byrne Cup to other venues.
Brendan Hackett's first competitive game in charge of the Westmeath footballers against DCU has been switched from Cusack Park in Mullingar to the nearby St Loman's pitch.
Meanwhile, the Kilkenny footballers will now host Offaly at Freshford. Both games will still have a 2pm start.
Laois v DIT will kick off the 2010 O'Byrne Cup under floodlights at Graiguecullen on Saturday night, while Kildare v UCD, Carlow v Athlone IT, Wicklow v Louth, Dublin v Wexford and Longford v Meath all have 2pm throw-ins on Sunday.
Currently, the rest of the weekend's GAA fixtures will go ahead as scheduled.
The clash of Armagh and UUJ will get the Barrett Sports Lighting Dr McKenna Cup underway on Saturday at Crossmaglen. Later that night there are 7pm starts for Cavan v Donegal and Down v Queen's University.

Meanwhile, the Connacht FBD League begins on Sunday with Sligo IT v Roscommon and Mayo v NUIG the pairings in Group A, while Galway face Sligo and Leitrim host GMIT in Group B.
