Johnny Sexton has been ruled out of Leinster's Heineken Champions Cup opener against Racing 92 in Le Havre tomorrow, as Ross Byrne continues to deputise at out-half.
Sexton has not yet recovered from the calf issue that hampered him on Ireland duty last month.
Leinster have been dealt another major blow ahead of their trip to France, as Tadhg Furlong's troublesome ankle sees him also miss out.
Michael Ala'alatoa replaces Furlong, with Cian Healy providing tighthead cover on the bench.
Ryan Baird is rewarded for his good showing in last weekend's win over Ulster, as he starts in the back-row at the expense of Jack Conan, who has to make do with a place on the bench.
Garry Ringrose continues as captain in the centre, alongside Charlie Ngatai, while Jason Jenkins partners James Ryan in the second-row.
The versatile Jamie Osborne is in line to make his European debut from the bench.
