Coaches Anthony Foley and Ian Costello once again maintain consistency in selection, with just three changes from the side that came from 12-0 down at half-time to beat Neath 21-12 at the Gnoll last time out.
Two of those changes come about as a result of injury. Centre Tom Gleeson, who got injured in the Neath game, is replaced by Richmond clubman Mike Kelliher, while hooker Mick Sherry returns from injury in place of Sean Henry.
Foley and Costello have their young and talented side playing an exciting brand of rugby and the game affords the province's supporters the opportunity to see first hand the next generation of Munster players in action.
