Two of Sunday’s Championship matches have been postponed because of frozen pitches, with a number of others called off elsewhere in the EFL.
The 12:00 GMT kick-off between Sheffield United and Oxford United and Portsmouth’s game against Ipswich at 15:00 are both off.
In a statement, the Blades said a referee looked at the Bramall Lane pitch before the scheduled start and found parts of the playing surface were frozen.
The game at Fratton Park was postponed following a pitch inspection at 11:00 GMT.
Ten fixtures have also been called off in League Two and four more have fallen to the freezing weather in League One.
In League One, Doncaster’s meeting with Luton, Barnsley’s trip to Port Vale, Rotherham v Mansfield and Stevenage against Leyton Orient were all called off on Sunday.
In addition to five of Sunday’s League Two fixtures which had already been postponed on Saturday, Barnet v Crewe, Barrow v Bristol Rovers, Cambridge v Grimsby, Colchester v Accrington and Newport v Tranmere failed pitch inspections.
