Damar Hamlin Injury Explained By DR Sutterer

This was one of the worst injuries i can remember in NFL History and I have been watching for 25 years. Damar Hamlin suffered Cardiac Arrest after this hit but for about 3 seconds appeared to be fine standing up adjusting his face mask before collapsing and receiving CPR right on the field before being taken away in an ambulance and taken to University of Cincinnati Medical Center. This was so bad but i was happy to see the NFL Postpone the remainder of the game to a time to be determined later. The Buffalo Bills and Cincinnati Bengals players both seemed to be distraught. Below is the original link to Dr Sutterer's Video and thoughts and prayers to his family.
