Please see below official return to play protocol as published on the RFU website
As our understanding of concussion has improved it is clear that there is significant variability in recovery from concussion. Subtle chemical changes in the brain can now be detected and more sophisticated scans and brain function tests are shedding more light on this.
Any return to play should therefore be assessed on an individual basis and should reflect the level of medical expertise available. Ideally, the club/school doctor or the medical practitioner responsible for the player’s health care will advise on and oversee the return to play process. However it is appreciated that not all GPs or school doctors have a detailed understanding of this process and engaging NHS health care professionals in such a process can be very difficult. Coaches and/or parents may therefore find it useful to refer the doctor to this guidance and the resources for healthcare professionals available on this site.
