Following up: The word on concussions

Those who enjoyed our November piece on concussion diagnosis featuring Seattle Seahawks team doctor Stan Herring can get a better feel for Herring and the evolving concussion protocol through the video above.

Herring, speaking with ESPN injury expert Stephania Bell from the NFL scouting combine, points to a significant human element in the diagnosis process. He stressed in November and again on this video the need for team medical personnel to know players' personalities and tendencies. That information makes it much easier to pick up on abnormalities.
