@George,
My heart goes out to the Buffalo Bills player Damar Hamlin after his collapse after a tackling collision with a Bengals player. He received CPR on the playing field to successfully restart his heart after cardiac arrest.
The game was temporarily suspended and was later on postponed by the NFL.
He’s currently on the critical list on a respirator in a Cincinnati hospital, apparently in stable condition. Our thoughts and prayers go out to him and his family.
