Saturday’s racing at Newcastle has been called off because of frozen ground but it will go ahead at Newbury following an inspection.
Champion hurdler Constitution Hill was due to return in the Fighting Fifth Hurdle at Newcastle, which will now take place at Sandown on 9 December.
Stablemate Shishkin, who refused to race a week ago, was set to run in the Rehearsal Chase.
Newbury passed an inspection at 07:30 GMT on Saturday.
The entire track had been covered on Friday and was frost free at inspection time, allowing the Coral Gold Cup card to go ahead.
However, officials said they “will continue to monitor temperatures as they are expected to dip”.
