Leinster have received a major boost ahead of the United Rugby Championship semi-final against Bulls with Johnny Sexton recovering from an ankle injury to take place on the bench.
Sexton sustained the blow during the Heineken Champions Cup final against La Rochelle that forced him to miss the last weekend's quarter-final against Glasgow Warriors but James Lowe fails to recover from a shin injury.
The starting line up sees two changes as Robbie Henshaw replaces Ciaran Frawley at centre while Jack Conan comes in for Ryan Baird at the back row. The return of Conan sees Caelan Doris moving blindside.
Meanwhile, Bulls have named an unchanged line up for the weekend's game.
Leinster: O'Brien; Larmour, Ringrose, Henshaw, O'Loughlin; Byrne; Gibson-Park; Porter, Sheehan, Furlong, McCarthy, Ryan (capt), Doris, Van der Flier, Conan.
Reserves: Cronin, Healy, Ala'alatoa, Molony, Baird, McGrath, Sexton, Frawley.
Bulls: Moodie; Kriel; Hendricks, Vorster, Tambwe, Smith, Burger; Steenekamp, Grobbelaar, Smith, Steenkamp, Nortje, Coetzee (capt), Botha, Louw.
Reserves: Du Plessis, Matanzima, Hunt, Swanepoel, Steenkamp, Papier, Steyn, Arendse.
