There are several changes to the pack with Heinke van der Merwe joining Ireland duo Sean Cronin and Mike Ross in the front row. Number eight Jamie Heaslip forms an experienced back row alongside Shane Jennings and Kevin McLaughlin - who makes his 75th Leinster appearance, while Sean O'Brien (knee) is an absentee.
The backline is unchanged from the side that started last weekend's Heineken Cup final with Eoin Reddan linking up with Jonathan Sexton at half back and Gordon D'Arcy continuing at centre alongside Brian O'Driscoll.
Cian Healy (dead leg) will face a late fitness test, while All Black Brad Thorn is named amongst a strong replacements bench for Sunday's sold out encounter.
