Racing at Leopardstown today was called off when officials found the track to be waterlogged following heavy overnight rain.
After a 7.00am inspection racecourse manager Tom Burke said: "We're off unfortunately. Racing is cancelled due to waterlogging. We've had 16 millimetres of rain overnight and there is more to come in the next few hours as well."
It was later announced that today's card would be run on Sunday and Burke is hopeful the two remaining days of the Leopardstown Christmas Festival will beat the weather.
He said: "We're very hopeful we'll be OK by tomorrow because from noon today it is supposed to pick up and be dry right through tomorrow.
"It has all come so suddenly and it hasn't had chance to go away but we are hopeful we will go ahead tomorrow at this stage but we'll monitor the situation through the day as well."
Sunday's original line-up has been abandoned with the exception of the Evening Herald December Festival Hurdle, which will be run as the first race.
