Allen Park — While many NFL players and fans are still processing the jarring scene from Monday night, when Buffalo Bills safety Damar Hamlin went into cardiac arrest after a midfield collision and had to be resuscitated on the field, the moment brought back memories of another on-field tragedy for Detroit Lions defensive coordinator Aaron Glenn.
A third-year cornerback and kick returner with New York Jets in 1997, Glenn was on the sideline when Lions linebacker Reggie Brown required similar life-saving measures following a spinal cord injury that temporarily blocked his airway and ultimately left him paralyzed.
