Some Chiefs fans needed amputations after frigid playoff game, hospital confirms

• Hospital says fans suffered frostbite at Chiefs playoff game
• Kickoff temperature at Arrowhead was minus-4F (minus-20C)

Some of the people who attended the near-record cold Kansas City Chiefs playoff game in January had to undergo amputations after suffering frostbite, a Missouri hospital said Friday.

Research Medical Center didn't provide exact numbers but said in a statement that it treated dozens of people who had experienced frostbite during an 11-day cold snap in January. Twelve of those people - including some who were at the 13 January game - had to undergo amputations involving mostly fingers and toes. And the hospital said more surgeries are expected over the next two to four weeks as injuries evolve".
