Taysom Hill out for the season with torn ACL-additional damage per Rapoport [Hill placed on Injured Reserve on 12/6]

Yeah I remember watching that injury all to well when it happened. That was gruesome.

I’m hard pressed to think of a worse one live in TV as it happened.
There was a Bills player that broke his neck on a kick off during a pre-season game about 10 years ago. They did a procedure on the field that was experimental at the time that saved his life.
