Saturday's Football League action has been decimated as the freezing weather conditions tighten their grip on sport.
Three matches in the Championship have fallen foul of the cold spell and Leagues One and Two have been even harder hit, with only five of the 24 scheduled fixtures surviving inspections today.
Rugby and racing, too, have been badly affected, with no National Hunt racing in Britain set to take place until Tuesday at the earliest.
The Championship basement battle between Sheffield Wednesday and Peterborough is one of the biggest casualties, along with Reading's match at home to league leaders Newcastle, Watford v Sheffield United and Preston v Doncaster.
The pitch at Hillsborough is protected by undersoil heating but areas immediately surrounding the stadium have been covered in a thick blanket of snow, making roads and pavements in the vicinity treacherous.
Wednesday's chief executive, Nick Parker, said: "While we are still two days away from the fixture against Peterborough, the areas surrounding Hillsborough are covered in snow and ice. It is highly unlikely these areas could be cleared to the extent that would allow fans to come to the game and be guaranteed of their safety. Obviously the safety of our supporters is the club's main concern in these circumstances and we would not want to put fans in danger by encouraging them to use icy roads and pavements around Hillsborough."
Preston's match against Doncaster was called off after a lunchtime pitch inspection and earlier the League One matches between Brighton and Brentford, Charlton and Hartlepool and Oldham and Leyton Orient as well as the League Two game between Cheltenham and Hereford were also postponed.
A decision will be made tomorrow on whether Sunderland's Premier League home clash with Bolton on Saturday can go ahead. The city's Safety Advisory Group called an extraordinary meeting today to discuss the implications of the ongoing wintry conditions gripping much of the country.
The group, which comprises representatives of Sunderland City Council, police, ambulance and fire services as well as the club, will meet again tomorrow, with weather forecasts suggesting that conditions will worsen over the weekend.
Group chairman Ken Scott, of Sunderland City Council, said: "It is too soon at this stage to make a definitive decision regarding the status of the match. However another meeting will take place tomorrow after which we will make a further announcement. In the meantime, we will continue to monitor the weather conditions and associated safety issues."
In Scotland the early casualties include the fourth-round Scottish Cup ties between Ayr United and Brechin City, Forfar Athletic and St Johnstone, Raith Rovers and Airdrie United, Morton and Celtic and Kilmarnock and Falkirk.
The ties between Albion Rovers and Stirling Albion, Edinburgh City and Montrose, and Ross County and Inverurie Loco Works were all subject to 1pm pitch inspections this afternoon and failed.
In the Irn-Bru Scottish Second Division match between Cowdenbeath and Arbroath and the Third Division game between Berwick and Stranraer have also been called off.
