Yesterday in the Broncos-Bills game, the worst nightmare of every football player happened to Bills reserve tight end Kevin Everett. While covering a kickoff, Everett came out of a helmet-to-helmet hit with a fractured cervical spine. His spinal cord is intact, but he's still in a medically induced coma, some paralysis is likely, and there is still some chance he could die.
Every football player knows something like this could happen to him every time he steps on the field, but the chances are so remote that it's still a tremendous shock when it happens.
Please keep Kevin Everett in your thoughts; he'll be in my prayers.
