Leinster has restored Johnny Sexton to their starting line-up for their Champions Cup quarter-final against Saracens, who name Alex Goode at fly-half.
Sexton is back to captain Leinster after being left on the bench for their PRO14 triumph over Ulster last weekend, when Ross Byrne was preferred by head coach Leo Cullen.
There are two surprise selections for Leinster who hand European debuts to wing Hugo Keenan and flanker Will Connors for the match at the Aviva Stadium.
While Ronan Kelleher's inaccuracy at the lineout over recent weeks has raised enough concern within Cullen to start Sean Cronin at hooker.
The 72-cap forward scrums down in an all-Ireland front row of Cian Healy and Andrew Porter, but there is no place in the pack for PRO14 final Man of the Match Josh van der Flier who must settle for a place on the bench with Kelleher.
Victorious over Leinster in last year's final at Newcastle's St James' Park, Saracens are without Owen Farrell due to suspension and have opted for Goode at No.10.
Goode will form an experienced half-back pairing with scrum-half Richard Wigglesworth, but it is in the pack where the bulk of Saracens changes have been made.
Billy Vunipola, a tryscorer in the final 16 months ago, is joined in the back row by Mike Rhodes and Jackson Wray, who will make his 250th appearance for the three-time European champions.
Mako returns to the front-row alongside England teammate Jamie George and South Africa international Vincent Koch, while Maro Itoje is partnered by Tim Swinson in the second-row.
Replacements Alec Clarey and Dom Morris will earn their Champions Cup stripes should they enter the fray.
