The only other change in the pack sees Barry O'Mahony also return from injury to anchor the scrum, the front five remain the same with Sean Henry wearing the captain's armband.
In the backs, a knee injury takes Denis Hurley out so Johne Murphy swops the 11 jersey for the 15 with Ronan O'Mahony drafted in. While JJ Hanrahan, a late withdrawal from last week's game to provide cover for the senior side, is back in the number 10 jersey alongside Cathal Sheridan.
Munster lead this Pool on 13 points four clear of tomorrow's opponents but any ideas of complacency are dismissed by Defence Coach Mike Prendergast. "No I don't see any risk of that" he said after putting the squad through their paces in UL yesterday. "We've looked at our performance from last week and there are aspects of it that we weren't happy with. Obviously aspects we were delighted with. But the aim is to improve on that and that's the mindset we are taking into this game."
