Buffalo Bills star Damar Hamlin is in "critical condition," according to the NFL, after the 24-year-old safety collapsed Monday night during a game against the Cincinnati Bengals.
Team trainers got to Hamlin within 10 seconds of his collapse, footage shows.
CPR was administered to the player on the field before he was driven out of the stadium in an ambulance to a local hospital. The NFL has postponed the game.
