The freezing conditions get the better of the pitches at Doncaster Rovers and Crewe Alexandra.
League One's top two clubs have both had their matches this evening postponed because of frozen pitches.
Leaders Doncaster Rovers had been due to play host to Carlisle United at the Keepmoat Stadium, but following an inspection from a local official, the pitch has been deemed not playable.
Meanwhile, Sheffield United, who are in second spot, have seen their trip to Crewe Alexandra suffer a similar fate.
The postponements have come two hours after Oldham Athletic confirmed that their League One encounter against Hartlepool United had been cancelled because of the cold conditions.
