If a player shows symptoms of concussion before, during or after a match, that player must be removed from play immediately, not to return during that match. No Exceptions.
The player needs to be evaluated by appropriate medical staff. Best practice would be evaluation by a medical physician who has training in concussion evaluation and management. A player must do this before returning to play rugby in any form.
If a concussion is diagnosed, that player must sit out of activity with full rest for the minimum of 2 weeks (14 full days) AND be symptom free before beginning the 5 day Graduated Return to Play Protocols. Not returning to contact rugby before GRTP fully complete and symptom free.
Once a player is cleared by a physician, they should be closely monitored for any lingering symptoms by coaches, parents, teammates and medical staff and be removed from play immediately if symptoms occur.
