A former senior international rugby administrator says World Rugby must change when it comes to player welfare. David Moffett was the head of New Zealand Rugby in the late 90s, Australia's National Rugby league in the early 2000s, he headed Sport England briefly in 2002 and was head of the Welsh Rugby Union from 2002 to 2005. He's part of a new lobby group Progressive Rugby, pushing for urgent changes in rugby union rules to protect players from traumatic brain injuries. David Moffett says World Rugby is lagging behind other codes and needs to wake up and recognise that player welfare issues are not going away.
