The Buffalo Bills are no strangers to the life-and-death dangers of playing football. Last year, Damar Hamlin's medical crisis on the field against the Bengals was a chilling reminder of how football players put their lives on the line.

So the serious-looking injury to Bills running back Damien Harris on Sunday Night Football sparked major concern and brought back all sorts of memories.

Harris was hit on a carry in the second quarter and went down. Trainers tended to him immediately and called for an ambulance to be brought out onto the field.

The need for an ambulance in that situation is obviously a worry. The good news is Harris gave a thumbs up as he was being loaded into the ambulance.

Hamlin wasn't active for Sunday's game but he was on the Bills sideline. Cameras captured him showing clear concern for his teammate.

According to the NBC broadcast, the Bills delivered an update that Harris has a neck injury. He has movement in his extremities and is on the way to an area hospital for evaluation.

Those are good signs. The hope is that more good news follows. Harris' well-being is the top priority.

The Patriots drafted Harris in the third round of the 2019 NFL Draft out of Alabama. He twice had 1,000-yard seasons with the Crimson Tide, amassing 23 touchdowns in four seasons of action.
