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.
