The Leinster club senior football championship final between St Loman's and Moorefield and the All-Ireland club SFC quarter-final involving Fulham Irish and Corofin have both been postponed due to adverse weather.
The Leinster final was due to be played in Portlaoise this afternoon, but has been postponed due to snow on the pitch.
Temperatures plummeted in Laois overnight and with significant falls of snow, the decision has been taken to call the game off.
The final will be rescheduled for Sunday 17 December in O’Moore Park with a 2.00pm throw in.
Corofin's clash with Fulham Irish in Ruislip suffered a similar fate with heaving snow in London making the pitch unplayable.
A new date for the re-fixed match will be announced later in the week
