England's Owen Farrell has been passed fit to start for Saracens in their Champions Cup quarterfinal against Leinster in Dublin.
Farrell was a doubt due to a quad injury but will face Johnny Sexton for the second time in three weeks, having lost out to the Irish fly-half in the final game of the Six Nations at Twickenham.
Despite undergoing cheekbone surgery earlier this week, Brad Barritt starts in midfield alongside Marcelo Bosch, while Mako Vunipola starts in the front row alongside Jamie George.
Leinster have a full-strength team to pick from with Rob Kearney at fullback, Garry Ringrose at centre and Sexton being partnered by Luke McGrath at half-back.
Cian Healy, Sean Cronin and Tadhg Furlong make up a strong front row, while Dan Leavy, Jordi Murphy and Scott Fardy make up the back row.
Leinster: R. Kearney, McFadden, Ringrose, Nacewa, Lowe, Sexton, L. McGrath; Healy, Cronin, Furlong, Toner, Ryan, Fardy, Leavy, Murphy.
Replacements: Tracy, J. McGrath, Porter, Ruddock, Deegan, McCarthy, Carbery, O'Loughlin.
Saracens: Goode, Williams, Bosch, Barritt, Maitland; Farrell, Wigglesworth; M Vunipola, George, Figallo, Itoje, Kruis, Isiekwe, Burger, Wray.
Replacements: Brits, Barrington, Lamositele, Day, Cowan, Spencer, Lozowski, Wyles.
