Leo Cullen's side need to win in France to ensure a home quarter-final in the Champions Cup
Leinster have made three changes for Friday night's Champions Cup game against Castres in France.
Leo Cullen's side are guaranteed top spot in Pool 4, but they need to win to ensure a home quarter-final on the opening weekend of March.
There are no changes in the backs as Isa Nacewa captains the side from full-back. Adam Byrne and Rory O'Loughlin continue on the wings.
In the centre, Robbie Henshaw and Garry Ringrose continue their partnership, with Luke McGrath and Johnny Sexton completing the backline selection for Cullen.
All three changes come in the pack for the game with Cian Healy and Richardt Strauss coming into the side. They join Tadhg Furlong in the front row.
The final change comes in the second row as Ross Molony joins Devin Toner in the middle of the pack. Last weekend's man of the match against Montpellier, Jack Conan is joined by Josh van der Flier and Jamie Heaslip to complete the lineup.
Leinster team and replacements to face Castres:
(15-9): Isa Nacewa (capt), Adam Byrne, Garry Ringrose, Robbie Henshaw, Rory O’Loughlin, Johnny Sexton, Luke McGrath.
