The Wild Card Round matchup between the Kansas City Chiefs and Miami Dolphins was so frigid—temperatures at Arrowhead Stadium dipped to minus-4 degrees Fahrenheit with a windchill of minus-27 degrees—that a number of fans in attendance came down with severe frostbite that could require amputations, per Dave D'Marko of Fox 4 Kansas City.
Per that report, the medical director at the Grossman Burn Center at Research Medical Center, Dr. Megan Garcia, said that 70 percent of the patients referred to the center with frostbite in January were advised to have amputations, and many of them were Chiefs fans who attended the Dolphins matchup.
