Wednesday's meeting at Leopardstown has been cancelled following an inspection on Tuesday morning.
Parts of the course are reported to be unraceable after recent heavy rain.
The track's racing manager Nessa Joyce tweeted: "Unfortunately racing @LeopardstownRC tomorrow has to be cancelled. Areas of the track are unfit for racing. #disappointed."
HRI later announced that the card has been rescheduled for Monday, 15 April.
