Declan Kidney has made three changes for Saturday's RBS 6 Nations finale against Wales as Ireland attempt to win a first Grand Slam since 1948.
Number eight Jamie Heaslip, hooker Jerry Flannery and scrum-half Tomas O'Leary have all been reinstated following the 22-15 RBS 6 Nations victory over Scotland.
Heaslip, try scorer against the Scots, edges out Dennis Leamy who injured a shoulder at Murrayfield, while Flannery replaces Ulster's Rory Best and O'Leary reclaims the scrum-half shirt from Saturday's man of the match Peter Stringer.
Munster veteran Stringer created Heaslip's try with a superb break and his delivery was crisp throughout, but he has not done enough to be retained.
Kidney has retained Gordon D'Arcy at inside centre with Paddy Wallace continuing on the bench.
Kidney said: "The difference between the players is so small. The changes were partly for tactical reasons. It's about getting the right chemistry."
Victory in Cardiff would complete the Grand Slam and claim Ireland's first championship title since 1985.
Wales need at least a13 point win to keep the trophy.
