Can I still play sport with a concussion?
Short answer. No. A player with a suspected concussion comes off straight away and does not go back on that day, even if they say they feel fine. The national rule is "If in doubt, sit them out."
The Australian Concussion Guidelines for Youth and Community Sport (Australian Institute of Sport, June 2024) say a player with a suspected concussion is removed from sport immediately, with no return on that day. They should not be left alone at first or sent home by themselves, and they should be seen by a health care practitioner.
Some signs mean the player needs emergency care now, such as neck pain, a seizure, loss of consciousness, repeated vomiting, a severe or worsening headache, or increasing confusion. Call Triple Zero (000).
For community and youth sport the guidelines set minimum times before a return: at least 14 days without symptoms (at rest) before contact training, and at least 21 days from the day of the injury before competitive contact sport. The 14 days start when the symptoms stop, not on the day of the knock.
This is general information, not medical advice. The player's own doctor or health care practitioner guides their recovery and return, and your sport may have its own concussion policy as well.
