Leinster have been boosted by the return of Robbie Henshaw to their side to face the Scarlets in the Champions Cup semi-final at the Aviva Stadium tomorrow (kick-off 3:30pm).
Henshaw has been out of action since injuring his shoulder in Ireland's 6 Nations clash with Italy in February.
He'll return to the centre to partner Garry Ringrose.
However, in a blow to Leo Cullen, scrum-half Luke McGrath has NOT been passed fit to play, which means Jamison Gibson-Park will start alongside Johnny Sexton.
With Gibson-Park and Scott Fardy in the starting line-up, non-european player limits means there's no place for winger James Lowe.
Instead, Isa Nacewa will move out to the wing, with Fergus McFadden and Rob Kearney making up the back three.
In the pack, Australian Fardy resumes his place in the back-row like he was against Saracens, where he's joined once-again by Dan Leavy and number 8 Jordi Murphy.
James Ryan and Devin Toner make up the second row, with Cian Healy and Tadhg Furlong propping either side of hooker Sean Cronin.
