Tomorrow's meeting at Kempton will have to pass a 9am inspection if it is to go ahead.
Today’s fixture was staged as planned but two morning checks were required before the meeting could be given the thumbs up.
With another cold night in prospect, officials have decided to assess conditions in the morning.
The track tweeted: “We are holding a 9am inspection on Sunday morning ahead of the afternoon fixture. Seven races, first race 1.55pm”
