I had a couple of concussions years ago. One in the service and one in a swimming accident. Both times the doctors told me to lay off and not get my bell rung again for awhile because a second concussion too soon can have serious long term side effects. I'm all for Mayfield playing because Trevor Knight has regressed so much he's a joke of a QB. But all it takes is just one POS to "do a dirty" and then we would be SOL for the rest of the season. Baker Mayfield's guardian angel needs to have a good day Saturday.
