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.
Billy Holland came on as a second half replacement at the Gnoll and not surprisingly keeps the number 6 jersey on the strength of a good performance then and an equally impressive showing last weekend in the Magners League game against the Dragons.
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.
