Fans wrap up warm as the cold bites during Sunday's NFL game between the Green Bay Packers and the San Francisco 49ers at Lambeau Field in Wisconsin. The temperature was measured at four degrees Celsius, but with wind chill it felt like minus 14. Jonathan Daniel/Getty Images
The weather in Green Bay was a far cry from conditions in San Franciso, where temperatures were set to hit a comparatively balmy 13 degrees on Monday. Jonathan Daniel/Getty Images

San Francisco quarterback Colin Kaepernick eschewed such measures, playing without gloves and in short sleeves as he led his team to a 23-20 win. Kaepernick grew up in Wisconsin and was a childhood Packers fan. Ronald Martinez/Getty Images
So concerned was 49ers coach Jim Harbaugh by the conditions that he asked his quarterback to wear gloves and long sleeves three times before Sunday's game. Jonathan Daniel/Getty Images

The temperature during the match was minus 13, a bone-chilling minus 48 when factoring in wind chill, making it the coldest game in NFL history. Ronald Martinez/Getty Images
