The other switch sees Jamison Gibson-Park make his first start of the competition, with Conor Murray on the bench.
Dan Sheehan keeps his place at hooker, despite suffering a shoulder problem in the win over Scotland, but Ronan Kelleher is ruled out with Rob Herring among the replacements.
Eadestown's Jimmy O'Brien is also on the bench.
