Racing at Naas on Sunday has been cancelled and moved to next Friday due to a frozen track.
Following an inspection this afternoon, the track was found to be unfit for racing.
The two-mile four-furlong Grade One Ballymore Novice Hurdle had been due to take place, with nine horses declared.
Clerk of the course, Brendan Sheridan, said: "Having walked both tracks, parts of both are frozen.
"There is a frost warning this evening and temperatures tonight will go as low as -4. Unfortunately we will have to cancel."
It will now be rescheduled to take place on Friday, 9 January, including the feature.
There will be no jumps action in Britain on Sunday after both Plumpton and Chepstow called off their cards due to frozen tracks.
Frost covers were put down at Plumpton earlier in the week ahead of a card that was due to feature the Sussex National, but clerk of the course Marcus Waters called a precautionary inspection for Saturday lunchtime.
