Gordon D'Arcy is one of five players in total - including the back row trio of Jamie Heaslip, Shane Jennings and Sean O'Brien as well as prop Cian Healy - who will be making their seasonal debuts for Leinster after their involvement in the Rugby World Cup.
Isaac Boss again partners Jonathan Sexton at half-back, with D'Arcy linking up with Fergus McFadden at centre and Isa Nacewa returning to the right wing after being rested last week.
Up front, Healy joins Richardt Strauss and Mike Ross in the front row with skipper Cullen starting in the second row alongside Devin Toner.
Brian O'Driscoll, after further testing, has been given an extra week to recover from the 'stinger' he suffered during the World Cup.
The likes of Sean Cronin, Kevin McLaughlin, Eoin Reddan and Rhys Ruddock have been included on the replacements bench for the game which is already set to be played in front of over 46,000 supporters and counting, making it the third largest attendance in league history.
The previous record crowd of 48,000 attended 'The Last Stand' - Leinster v Ulster - at Lansdowne Road on New Year's Eve in 2006.
