In this first ever Players Matters Q&A, Chief Medical Officer Prof Eanna Falvey is joined by Dr Martin Raftery and Dee Keating, who have developed and headed up the creation of World Rugby's Brain Health Services. They address questions from the rugby community on what has been learned and what will happen next.

We also discuss GRTP in players with concussion history, and the latest innovation in instrumented mouthguards, an LED light that will enhance the efficiency of alerts when players experience significant head impacts.
