On January 2, 2023, in front of a national TV audience, Buffalo Bills safety Damar Hamlin made a tackle against the Cincinnati Bengals, stood up, and collapsed. His heart had stopped. Within seconds the medical staff were on the field, and assistant athletic trainer Denny Kellington, who had joined the Bills in 2017, started CPR. Doctors said Hamlin lost his pulse and had to be revived with CPR and a defibrillator, and that the quick response saved not only his life but his brain function. Head coach Sean McDermott said Kellington stepped up and took charge, and he credited him with saving Damar’s life.
