Former Wales forward Alix Popham believes rugby is still not dealing with the problem of head injuries – and fears a generation of young players are going to ignore the sport. Popham, who won 33 caps between 2003 and 2008 and played in two World Cups, was diagnosed two years ago with probable chronic traumatic encephalopathy at the age of just 40. He says the rugby authorities are “not learning” from the ongoing experience of players and studies linking rugby to brain injury.
