Johnny Sexton returns to Leinster's starting XV for Saturday's Heineken Champions Cup quarter-final against Saracens, while Seán Cronin has been recalled to the front row ahead of Rónan Kelleher.
Sexton had been rested for last Saturday's Guinness Pro14 final win over Ulster, making a late cameo as Ross Byrne featured.
But Leo Cullen has restored Sexton to his starting side for the visit of Saracens in a half back partnership with Luke McGrath.
Will Connors has been added to the back row to make his European debut with Josh van der Flier dropping to the bench, while Jack Conan and Caelan Doris retain their places.
Jordan Larmour starts at 15, with Hugo Keenan, another European debutant, and James Lowe on the wings. Garry Ringrose and Robbie Henshaw form the midfield pairing, while the pack sees James Ryan alongside Devin Toner in the second row behind props Cian Healy and Andrew Porter and Cronin winning his place at hooker ahead of Kelleher.
