Jamie Heaslip - who came off the bench in Edinburgh to score the only try of the match in Ireland's 22-15 victory over Scotland last weekend - is back in the starting line-up for the 2009 RBS 6 Nations Championship decider against Wales at the Millennium Stadium on Saturday.
Heaslip reclaims the No 8 jersey from Denis Leamy in one of the three changes coach Declan Kidney has made as Ireland go in search of only their second Grand Slam title to go alongside the solitary one notched up 61 years ago.
Ireland have won three of the four matches played at the Millennium Stadium since the five nations became six and, on top of their four-from-four record so far this time around, they also boast a superior points advantage over Wales.
In a second change to the pack Jerry Flannery returns to the starting hooker's position after featuring as a second half replacement against Scotland for his fourth start of the championship, with Rory Best reverting to the bench for the game.
The final change is at scrum half, Tomas O'Leary coming back into the side and swapping places with Peter Stringer.
Kidney said: "The difference between the players is so small. The changes were partly for tactical reasons. It's about getting the right chemistry."
