Hugo Keenan is in line to make his first appearance since the November victory over Australia after Leinster confirmed he's fully fit for Sunday's Investec Champions Cup collision with La Rochelle.
Keenan hurt his wrist during the 22-19 win over the Wallabies at Aviva Stadium.
Leinster said on Tuesday he is available for the trip to France, as are Jack Conan, Ciarán Frawley, Thomas Clarkson and Max Deegan.
Conan sustained an injury against Connacht four days before Christmas, while Frawley hurt his back against Bristol Bears earlier in the month. Clarkson has overcome the arm injury he picked up in the defat of Clermont, and Deegan has come through the graduated return to play protocols.
In another boost, Tadhg Furlong has not been completely ruled out. The province said he's due to step up his rehabilitation from a hamstring injury this week and will be further assessed before a final decision is made on his availability.
Jamie Osborne, Jordan Larmour and Tommy O'Brien came through the Munster game with no issues after their returns from lay-offs.
Dan Sheehan is still recovering from the ACL injury he suffered last summer, but he has returned to on-field training.
