Leinster travel to Kingspan stadium to face rivals Ulster with all current internationals on six nations duty.
The timing of this interprovincial fixture needs to be questioned in the wider relevance of the URC.
Luke McGrath will captain the side for the interprovincial clash. McGrath’s partnered at half-back by Ross Byrne while there's a change in the midfield as Rory O'Loughlin comes in to partner Jamie Osborne.
Jimmy O'Brien retains the number 15 shirt with Adam Byrne and Tommy O'Brien on the wings.
Up front, there's a new look front row as Ed Byrne, James Tracy and Michael Ala'alatoa all come into the line-up.
Ross Molony and Joe McCarthy are once more packing down in the second row while the back row is also unchanged, Rhys Ruddock, Scott Penny and Max Deegan completing the forwards.
From the replacements, Cullen can call upon Seán Cronin, new centurion Peter Dooley, Thomas Clarkson, Devin Toner, Dan Leavy, Nick McCarthy, David Hawkshaw and Martin Moloney.
