Don't forget that Ohio has a Return-to-Play law that was enacted in 2013 and covers concussions in youth sports. As of April 26th, 2013, Ohio law (ORC 3707.511) requires a youth sports organization to provide this sheet to the parent or guardian of an individual who wishes to practice for or compete in an athletic activity organized by the organization.
