A player in any sport being placed in concussion protocol has become as common as players dealing with ankle sprains. In contact sports -- even in non-contact sports -- concussions happen.
It's something the Steelers are dealing with this week as placekicker Chris Boswell works his way through the levels of protocol after suffering a concussion in last Sunday's 15-10 win over the Browns.
The idea of concussion protocol began back in 1990 in Pittsburgh because of a simple question asked by then-head coach Chuck Noll regarding the status of quarterback Bubby Brister.
