Pro Football Hall of Fame quarterback Joe Namath doesn't remember ever suffering a concussion or going through concussion protocol. Such terms didn't exist 40 years ago.
In Namath's playing days, they called a concussion “getting their bell rung,” as he recalls. Not much was known about concussions or the long-term effects. The former New York Jets star, who was as influential off the field as he was on it, is now leading the charge for treatment of brain injuries for those who played when concussions weren't fully understood.
