Principality Welsh Rugby Union Podcast 49

We take a special look at the state of refereeing in Wales in this week's Principality Welsh Rugby Union Podcast. We hear from WRU National Match Officials Manager Nigel Whitehouse, as well as from one of the school hub officers where pupils are getting the chance to take up the whistle. We also hear from two scrum halves, Tom Habberfield at the Ospreys and Gareth Davies at the Scarlets, about this week's Champions Cup challenges.
