Bills safety Damar Hamlin was taken off the field in an ambulance after receiving treatment for over 10 minutes, which resulted in the game between Buffalo and the Cincinnati Bengals being suspended until further notice Monday night.

CPR was administered to Hamlin on the field for multiple minutes after he collapsed on the field following a play in the first quarter. He appeared to be receiving oxygen as he was placed in the ambulance and taken off the field some 16 minutes after he collapsed.

The injury took place after Hamlin tackled wide receiver Tee Higgins and quickly got up afterward. He then abruptly collapsed with athletic trainers coming to help immediately. A stretcher was immediately brought to the field as athletic trainers protected his head.
