Can rugby concussion be tackled by protective headgear?
There is "potential" to reduce concussion in rugby by introducing new protective headgear, an expert has said.
Cardiff University and its partners got £165,000 via a competition co-sponsored by America's National Football League to develop an anti-concussion material.
World Rugby has previously said evidence does not suggest headgear prevents concussion.
Dr Peter Theobald, of Cardiff University, said its C3 material could help in rugby but it could potentially change aspects of the game.
