Leo Cullen has named his squad to face Northampton.
Leinster could hand as many as five European debuts to youngsters in tomorrow's champions Cup clash with Montpellier.
Jamie Osbourne makes his from the outset, coming in at outside centre.
On the bench, Vakh Abdaladze, Jack Dunne, Academy scrumhalf Cormac Foley and Scott Penny, are all in line to play their first games in the Heineken Champions Cup should they be introduced at the GGL Stadium.
The Leinster Rugby squad and staff will leave Dublin airport tomorrow morning, Friday, ahead of the late evening kick-off in France (8pm).
