there is the protocol, it is clear!
4. What is the role of contest officials in administering the new rule?
Officials are to review and know the signs and symptoms of concussion and to direct immediate removal of any athlete who
displays these signs or symptoms,
An official shall not permit the athlete who has been removed under this rule to return to competition without written medical
authorization presented to the head official.
If a contest official is aware that a student has been permitted to return to competition without written authorization from a
physician or licensed athletic trainer, that official shall immediately stop play and remove that student from competition and report
the incident to the Ohio High School Athletic Association
Note that officials are not medical professionals and have no authority to determine whether or not student has sustained a
concussion. The official is responsible for directing removal when he or she observes signs and symptoms that may indicate a
student is concussed.
