EXPLAINER: What happened to Damar Hamlin?

Buffalo Bills safety Damar Hamlin suffered a cardiac arrest after making a tackle during Monday night’s game, causing the NFL to suspend a pivotal game against the Cincinnati Bengals that quickly lost significance in the aftermath of a scary scene that unfolded in front of a national television audience.

“Damar Hamlin suffered a cardiac arrest following a hit in our game versus the Bengals. His heartbeat was restored on the field and he was transferred to the UC Medical Center for further testing and treatment,” the Bills said in a statement released early Tuesday. “He is currently sedated and listed in critical condition.”
