Leinster boss Matt O'Connor makes seven changes for the trip to Scarlets
Leinster head coach Matt O'Connor has reshuffled his team for tomorrow's clash with Scarlets at Parc Y Scarlets (kick-off 5.15pm, live on Sky Sports).
Luke Fitzgerald returns to the back three alongside Fergus McFadden and Zane Kirchner in the back three.
Ben Te'o, who was cleared to play this weekend after appearing before a disciplinary hearing following an alleged strike to an opponent's head, partners Gordon D'Arcy in the centre.
Eoin Reddan comes in to partner Jimmy Gopperth in the half-backs.
There are five changes in the pack with Cian Helay, Sean Cronin and Marty Moore starting. It is Healy's first start for Leinster since the opening day trip to Glasgow Warriors in September.
Like Fitzgerald, Mike McCarthy was also retained by the Irish management last weekend, and comes into the second row to partner Kane Douglas who makes his 20th appearance for Leinster.
In the back row Rhys Ruddock captains the side from blind side, with Dominic Ryan starting at open side. Jack Conan is once again selected at the base of the scrum having recovered from the ankle injury that forced him out of the starting XV before kick off last Friday.
LEINSTER: (15-9) Zane Kirchner, Fergus McFadden, Ben Te'o, Gordon D'Arcy, Luke Fitzgerald, Jimmy Gopperth, Eoin Reddan; (1-8); Cian Healy, Sean Cronin, Marty Moore, Mike McCarthy, Kane Douglas, Rhys Ruddock (c), Dominic Ryan, Jack Conan.
Replacement: (16-23) Richardt Strauss, Michael Bent, Tadhg Furlong, Tom Denton, Josh van der Flier, Isaac Boss, Noel Reid, Dave Kearney.
