Peter King writes about the somber mood in Buffalo's locker room following the loss to Denver, a mood that had everything to do with tight end Kevin Everett, who went down hard after a collision with Denver's Domenik Hixon on a kickoff return. Everett suffered a cervical spine injury, underwent surgery last night, and news about his condition will be released after the swelling goes down, according to doctors. We can only hope for the best.
