Return to play protocol should follow a stepwise progression as follows:
Step 1: No activity until asymptomatic at rest and with exertion
Step 2: Light aerobic exercise (walking, stationary bike)
Step 3: Sport specific, non-contact activities (running drills)
Step 4: Non contact training drills (passing drills, begin weight lifting)
Step 5: Full contact practice (following medical clearance)
Step 6: Return to play (normal game play)
Each step above should take 24 hours. If any symptoms occur, the athlete should drop back to the previous level and try to progress again after 24 hours of rest has passed.
