Concussion in sport - 'The biggest hit I've ever had'

Available for over a year

Shane Williams, former Wales and Lions rugby international, says he often asks himself the same question: "Has my memory deteriorated because of my age? Or is it because I’ve taken hits over the years?" In this episode of 5 MINUTES ON, BBC News Wales Correspondent, Tomos Morgan, meets his hero to talk about the injuries he suffered while at the top of the sport. Williams opens up about the past injuries that didn't concern him at the time, but that he worries about now. It's as a new study, by researchers at the University of South Wales, suggests a rugby players' cognitive function can decline after just one season.
