Buffalo Bills safety Damar Hamlin drove off the field in an ambulance during a Monday night game against the Cincinnati Bengals after colliding with Bengals wide receiver Tee Higgins.

Hamlin made a tackle during a kickoff at the Cincinnati Bengals. After completing a tackle on Higgins, Hamlin stood straight up and took a step forward before stopping and collapsing backwards.

The Bills players immediately waved off the sideline to seek help from their coaching staff. Hamlin was down for about 10 minutes, with medical staff appearing to give Hamlin CPR before he was taken off the field.

Players from both teams crowded around him, with both sides looking distraught. The Bills team came together in group prayer as he was taken away.

The game at Paycor Stadium in Cincinnati has been suspended.
