in 2010, we spoke to jamie roberts on the physicality of the game.t evening, you just think to yourself, you know, that could have been... ..could have been much worse. you know, it could have been, you know, maybe a brain injury or something similar. in 2014, in another programme, welsh rugby legend jpr williams we interviewed a neuropathologist who'd long been concerned about head injuries in sport. so have things changed? seven years on, we caught up. it's a very slow and slightly frustrating process. i'm slightly depressed and disappointed that sports haven't kind of got together properly on this. why is it a particular problem in physical contact sports? concussion is a form of brain injury. what we believe is happening is, deep down in the brain, the rotational forces, as the head is impacted and the brain rotates inside the skull, that actually there's some stretch and sheer on very fine fibres and blood vessels in there, and that causes some functional change in the brain. rugby today takes concussion on the pitch very seriously. commentator:
