Injuries sustained in last weeks game against Ulster have ruled James Coughlan and Luke O'Dea out for a number of weeks and Denis Hurley and Ivan Dineen succumbed to illness this week forcing Rob Penney to ring the changes.
Ian Keatley comes in for Hurley at full back, a position he occupied for the latter end of the game last weekend while the loss of O'Dea who was in a rich vein of form is softened by the availability of international Simon Zebo.
Paddy Butler might have expected to be preparing for the A game later today against Connacht (Garryowen FC 5pm) but instead finds himself anchoring the scrum while after six games on the bounce Casey Laulala and Sean Dougall are given a break, Keith Earls in for Laulala at 13 with Niall Ronan back from injury to replace Dougall.
There's a return to the match day squad for Danny Barnes and a first time inclusion for JJ Hanrahan after his late show in Deramore Park when his try and conversion helped Munster A to a one point victory.
