The Championship games between Rotherham and QPR and Sheffield Wednesday against Swansea are among a number EFL fixtures postponed on Saturday because of frozen pitches.
In League One, games at Crewe and Blackpool are off and Oxford United against Wigan is delayed until Sunday.
League Two has been worst affected by the conditions, with 10 matches off including Oldham against Exeter.
Inspections are planned at other games over the next 24 hours.
In the National League FC Halifax against Dover, Notts County’s visit to Wrexham and Woking’s match with leaders Torquay have been postponed.
Oxford say they are confident rising temperatures will allow their pitch to thaw out by Sunday.
But the early call off at Oldham will come as a relief to Exeter, who travelled to Barrow in midweek, only for the game to be postponed an hour before kick-off.
A new date of Tuesday, 23 March has been agreed for the rescheduled fixture.
Carlisle against Crawley is also off in League Two, meaning the Cumbrian side have now been involved in 10 postponements since Christmas.
