Conor Finn has been brought into the side to replace Barry Daly on the right wing. Daly received a broken thumb in the clash with Wales and underwent surgery on Sunday. He is expected to be out of action for six weeks.
Diarmuid Higgins has been brought into the squad and will take his place on the bench, replacing Jake Cawley who took a knock during last Friday's game and is unavailable for selection this week.
Prop Cawley is due to be available for selection for the upcoming match against Italy.
Chris Farrell has been promoted from the bench to outside centre along with scrum half Luke McGrath, with the pair making their first starts of the Championship. Foster Horan and Kieran Marmion are the players to make way.
