Leinster have named nine of their Champions Cup-winning team to start against Munster in tomorrow's Pro14 semi-final but out-half Johnny Sexton misses out through injury.
Robbie Henshaw had already been ruled out earlier in the week but captain Isa Nacewa has been passed fit to start and lines up at first centre.
Five of the eight forwards named started against Racing 92 in Bilbao, with Jack McGrath, Rhys Ruddock and Jack Conan getting the nod for the RDS tie (3.15pm).
Ross Byrne comes in for Sexton, while Joey Carbery starts at full-back.
Meanwhile, Munster have made just one change to the team that defeat Edinburgh in the quarter-final two weeks ago.
John Ryan starts at tighthead in the absence of Stephen Archer.
Hooker Rhys Marshall, a try-scorer in the Edinburgh win, is set to make his 50th appearance.
Elsewhere, Robbie Diack, Callum Black and Charles Piutau will play their final games in Ulster colours after being named in the starting team for Sunday’s crunch Champions Cup play-off versus Ospreys (Kingspan Stadium, 3.05pm).
