Despite a recorded temperature of minus four degrees at kickoff, GEHA Field at Arrowhead Stadium was still packed with more than 70,000 fans Saturday night for the Kansas City Chiefs' Wildcard matchup against Miami.
As reported by Kansas City's ABC affiliate, KMBC, even with extra caution taken by many in attendance, the Kansas City Fire Department said Monday that it received 69 calls for service at Arrowhead on Saturday. That figure includes calls from both inside the stadium and in the parking lot.
Approximately half of the nearly 70 calls were hypothermia-related, KMBC reported.
According to the department, 15 people were transported to area hospitals. Among those hospitalized, seven were treated for hypothermia and three for frostbite.
These numbers do not include walk-ins to KU Medical Center aid stations. Inside Arrowhead, there were seven first aid stations around the stadium manned by EMTs and KU Medical staff.

Conditions at the game were cold enough to freeze water in seconds and crack a hole in Kansas City quarterback Patrick Mahomes' helmet.
The game is officially the coldest ever held at Arrowhead, as well as one of the five coldest in NFL history, KMBC reported.
