Plumpton inspect for Monday
Monday's meeting at Plumpton is subject to an 8am inspection on Sunday.
The ground is currently waterlogged in places following 13 millimetres of overnight rain.
Clerk of the course Mark Cornford is, however, remaining positive in light of a reasonable 24-hour forecast.
He said: "Ideally, I don't want any more rain. If that's the case, then there would be a live prospect of racing on Monday.
"That said, we had more rain than I'd expected overnight so we've gone back a step.
"We are trying our hardest to get the meeting on, but we do need it to stay dry."
