A new campaign is being launched to raise awareness of the dangers of concussion in sport.
Today Chris Bryant MP (Labour), and Baroness Grey-Thompson (Crossbencher) will chair a Parliamentary roundtable looking at the issue.
Members of the English and Scottish Rugby Unions, the Football Association and the Professional Footballer's Association will attend the roundtable, as well as leading concussion campaigners Lewis Moody, Rory Lamont and Peter Robinson.
It's hoped today's roundtable will be a chance for key figures in the sporting world to discuss what more can be done to ensure players of all levels of sport, play in a competitive but safe environment.
