Johnny Sexton will captain Leinster in the opening United Rugby Championship when they face Vodacom Blues in the Aviva Stadium.
Hugo Keenan, Rory O'Loughlin and James Lowe are the back three selected by Cullen with Keenan and O'Loughlin seeing action for the first time this season against the Bulls.
Ciarán Frawley will also get his first taste of Leinster action in the centre this season as will Garry Ringrose beside him, with both players now fully recovered from shoulder injuries.
In the half backs, Cullen has chosen the same pair as started against 'Quins with the experienced duo of Luke McGrath and captain Johnny Sexton starting.
In the pack Andrew Porter has recovered from a foot injury and will start in the number one jersey for Leinster for the first time since November 2016. Dan Sheehan starts at hooker with Michael Ala'alatoa making his competitive debut at tighthead prop.
Ross Molony and James Ryan will form an all-St. Michael's College second row unit when they line out tomorrow afternoon.
Finally in the back row, Rhys Ruddock, Josh van der Flier and Caelan Doris complete the starting XV for Cullen. Neither van der Flier nor Doris were involved at the Aviva two weeks ago.
On the bench, Cian Healy will wear the number 18 jersey, while Max Deegan will make his first competitive appearance for the club since October 2020 when he is introduced.
A crowd of 20,000 is expected in the Aviva stadium for the URC opener. The ground is operating at 75% capacity.
