It's now back to back starts for the Athlone man.
Ireland have made seven changes for Saturday's trip to Wales in the Six Nations
Robbie Henshaw has been moved to 12 with Gary Ringrose coming in at outside centre.
Two of the changes made by interim head coach Simon Easterby are enforced, with Ronan Kelleher and captain Caelan Doris both ruled out through injury for the game in Cardiff.
Dan Sheehan comes in to skipper the side at hooker with Jack Conan replacing Doris at number-eight.
Thomas Clarkson starts for Ireland for the first-time at tighthead prop, with Joe McCarthy in for Tadhg Beirne in the second-row.
Andrew Porter continues at loosehead with James Ryan alongside McCarthy in an all Leinster front-five.
Peter O'Mahony and Josh van der Flier start again on the flanks with an unchanged half-back pairing of Jamison Gibson-Park and Sam Prendergast.
The fit-again Mack Hansen starts on the right wing with James Lowe on the left.
Jamie Osborne comes in at full-back for his first start in the Six Nations while Jack Boyle will earn his first cap if brought off the bench.
