But besides that pair, coach Ian Costello is able to call on players such as Tommy O'Donnell, Stephen Archer, Scott Deasy, Tom Gleeson and skipper Billy Holland who have a wealth of RaboDirect PRO12 League experience to call on.
And Munster will need all that experience against a visiting side who are enjoying a rich vein of form right now. They haven't been beaten in five games since losing in Bedford in early October and are leading the Championship by a point over Bristol.
Last time out they beat the Andre Bester coached Rotherham Titans 30-13 and 15 of that match day squad will be on duty tomorrow night in Clonmel.
