That change comes in the front row where the fit again Jerry Flannery returns in place of Frank Sheahan.
Flannery injured a knee in the international against Argentina but has staged a remarkable recovery to regain his place in the starting XV.
Munster completed their preparations in UL on Wednesday and while Flannery took a full part, Barry Murphy sat out the afternoon session because of a slight back problem but that was purely precautionary and Murphy is fit and well and ready to take his place alongside Lifeimi Mafi in the Munster midfield.
