The selection by Westport to Hove was a non-runner.
The first race tomorrow is the 13:10 at Chelmsford.
Monday's jumps fixture at Market Rasen has been cancelled due to a frozen track. There is optimism that Plumpton will pass an 8am inspection tomorrow. While frost sheets were deployed in vulnerable areas on Friday the course was frozen in places on Sunday morning. Clerk of the course Mark Cornford said: "We were affected by frost this morning but we're certainly not frozen across the whole track. The forecast suggests we will have cloud cover from the early hours on Monday morning, so hopefully we don't have too much of a frost overnight."
