I had the following Letter in The Times about Head Injuries in Rugby Union published on 16th March 2017:
The Head Injury Assessment introduced by the Six Nations for players injured in a game is missing one important piece of information. The Assessment has no baseline. If a rugby player is not tested out of season using a brain scanner then when he or she is injured the doctor at pitch side has no reference point.
Until is there a baseline is players who have had an injury to the head in a game should go off and stay off. This is for their long term good.
I hope World Rugby will bring in baseline testing in time for the Rugby World Cup in Japan in 2019.
