All athletes thought to have a concussion should see a physician shortly after the event for professional diagnosis. They can then follow the Return to Play Guidelines and should return to their physician between Steps 4 and Step 5. Only the physician can give an athlete clearance to return to any contact-related activities.
Only a physician should determine when to return to sport/life/school/work. Often a physician may wish to consult other health care professionals when the issue of returning a student to the classroom arises.
