Re: Knocked out but played on
Or RFU Régulation 9 if you are in England
9.5 In respect of all other adult and age grade matches or training sessions, participants and all those involved (including coaches, players, parents and club officials) should refer to the RFU Headcase guidance set out in www.englandrugby.com/headcase/ for guidance on prevention, recognition, management and returning to play. All (players, coaches, parents, match officials and club officials) should familiarise themselves with this RFU Headcase guidance.
Ignorance is no defence.
9.6 Any individual who exhibits any of the signs or symptoms of concussion should be immediately and permanently removed safely from the field of play, should not return to play that day, and it is recommended that they are referred to a medical or healthcare professional for assessment and advice.
