Hereford United have called a pitch inspection for 1pm with most of the County still freezing.
Darlington's match with Chester and Rochdale's game with Notts County have already been postponed. Both grounds have frozen pitches, with temperatures across the country not expected to creep sufficiently above freezing for the matches to take place.
The only other League Two match, Stockport's game with Mansfield, will also face a 1pm inspection.
