Sunday's Dr McKenna Cup clash between Donegal and Derry has been called off due to safety concerns around travelling conditions to Letterkenny.
The game was scheduled to throw in at 1.30pm, with the pitch passing an inspection. However Ulster GAA later confirmed it would not be played.
"Despite the pitch being deemed playable, based on the current road conditions, it is unsafe for players, officials and supporters to travel to Letterkenny," a statement read.
Derry GAA posted their own statement, saying: "Due to the overnight weather and unsafe conditions on the road network, this afternoon's Dr McKenna Cup match vs Donegal has been called off. Please take care on the roads."
Three Walsh Cup games have also fallen foul of the weather.
After heavy overnight frost, Glenisk O'Connor Park which was due to host Offaly v Antrim, was deemed unplayable, while Kildare v Galway was cancelled after a late pitch inspection at St Conleth's Park. Westmeath v Kilkenny was also called off.
