Sunday's play-off clash between the Green Bay Packers and San Francisco 49ers could be the coldest game in NFL history.

An Arctic air mass is set to sweep the Midwest of the United States this weekend, meaning temperatures at Lambeau Field could dip lower than -25 degrees Celsius.
Even if the cold blast does not result in a record low temperature, the air in Green Bay is set to be -17C at the warmest when the game starts at 3.40pm local time.
All the tickets for the contest have been sold, ending fears that that Green Bay's 319-game streak of home sell-outs could end this weekend.
The NFL's coldest game based on outright temperature was also held at Lambeau Field and saw the Packers play the Dallas Cowboys in conditions of -25C in the 1967 NFL Championship Game.
However, the 1981 AFC Championship Game at Riverfront Stadium in Cincinnati - subsequently called the 'Freezer Bowl' - also has a claim for the coldest ever game as the wind chill was calculated at -51C, lower than in the 'Ice Bowl' of 1967.
The conditions at Lambeau Field this Sunday may pose particular problems for the travelling 49ers as temperatures in San Francisco peak at around 20C at this time of year.
Green Bay is not the only play-off venue struggling with extreme weather conditions, with the Philadelphia Eagles having to clear between 2-3 million pounds of snow prior to their clash with the New Orleans Saints on Saturday night.
The Cincinnati Bengals' clash with the San Diego Chargers on Sunday afternoon is also set to be played in temperatures around the freezing point.
