Ireland out-half Ciarán Frawley will start for Leinster in their BKT URC trip to Ospreys tomorrow night (7.35pm)
The 26-year-old is part of the Six Nations squad but hasn't featured in the wins over England and Scotland.
Fellow international squad members Jamie Osborne, Jack Boyle, Gus McCarthy and Jimmy O'Brien are also in Leo Cullen’s starting XV as the league leaders bid for an 11th successive win.
Luke McGrath captains the side, while academy duo Charlie Tector and Hugh Cooney have been selected in the centre positions.
RG Snyman is named among the replacements but New Zealand's Jordie Barrett is not in the squad.
"What playing role they have, let's wait and see because it’s trying to get the balance right," Cullen told RTÉ Sport earlier this week when asked about the marquee signings' involvement.
"Particularly with Jordie again, when he came in, you are trying to make sure we are looking after him as well because...both of those guys, as an example, weren't here last week because they’ve gone straight through the Rugby Championship.
"Obviously, RG picked up an injury, even Jordie picked up an injury, as in we try to look after them at this time of year, trying to get the right balance there."
Boyle and Rabah Slimani retain their places from last month’s win over Stormers, with McCarthy slotting into the middle of the front row at hooker.
Academy second row Diarmuid Mangan joins Brian Deeny in the engine room.
Meanwhile, James Culhane takes the number 8 shirt with the experienced duo of Scott Penny and Max Deegan on the flanks.
John McKee, Paddy McCarthy and Rory McGuire once again provide the front row cover as Snyman and Alex Soroka offer the rest of the reinforcements for the forwards.
Fintan Gunne joins Ross Byrne as the half-back cover for Friday night’s game, while Andrew Osborne is the final replacement.
