Aaron Glenn still is haunted by what he saw at the Pontiac Silverdome that day.
Glenn was a fourth-year defensive back playing for the New York Jets in 1997 when Detroit Lions linebacker Reggie Brown, Glenn's former college teammate at Texas A&M, suffered a career-ending spinal injury.
Brown was injured when a Jets lineman fell backwards into his neck as he made a tackle on what appeared to be a routine play. The injury caused Brown's esophagus to stop working, and as Brown went into respiratory arrest, Glenn remembers him turning "purple and blue" and getting CPR on the field.
