The Green Bay Packers' NFL wildcard play-off against the San Francisco 49ers was always going to be chilly - after all, Wisconsin in early January is never balmy at the best of times.
But the temperatures that players and fans had to brave turned out to be insanely cold: the match was played in minus 15 degrees celsius, with wind chill making it feel like -26.
Amazingly, that's not the record low for an NFL game: that was set at a match in 1982 that saw temperatures of -23... and a wind chill factor of -50!
Still, it was plenty cold enough: these conditions have been described as "once in a generation cold" due to the Polar Vortex sucking cold air down over the whole of North America.
And fans and players made the best of it in inimitable American style as they did their best to survive the chill:
On the pitch, it was the California-based side who came out on top......and no doubt losing only made it feel even colder for the Green Bay playersThis is the first time WoS has seen the word 'tundra' since GCSE geographyAmong those who can't grow facial hair, artificial beards were widespreadFor some, only the full-on 'Darth Vader' look was warm enoughNo talk of banning woolly hats and snoods in the NFL, naturally enoughEven in defeat, just being there was enough to make it all worthwhile for the game's survivors
