Sean O'Brien ruled out of Ulster clash with hip injury - but could return for Champions Cup pool finale
Leinster are hopeful that Lions flanker Sean O'Brien will be available for their concluding Champions Cup ties.
O'Brien was ruled out of the 21-18 win against Connacht in the RDS on New Year's Day with a tightness in his hip that affected him in December but the signs are pointing towards a return against Glasgow on Sunday week.
Joey Carbery returns to training this week following his broken arm but there is no indication yet as to when he is due to return, but it is unlikely to be in time for an involvement in the upcoming European action.
Leinster will chase an impressive hat-trick of inter-provincial successes against Ulster in Dublin this weekend despite parading vastly different line-ups in each game.
More changes are inevitable.
Rory O'Loughlin had a head injury assessment following his attempted tackled on Ultan Dillane in the final throes of yesterday's win and will undergo return to play protocols but he is unlikely to be risked this weekend.
Richardt Strauss picked up a back injury against Munster on St Stephen's Day and is improving but remains unavailable.
There was better news for the McGraths, with both Lions prop Jack and international scrum-half Luke passing their respective HIA protocols.
Dan Leavy was withdrawn with a back injury late in the first-half against Connacht and will be further assessed before head coach Leo Cullen makes his final selection on Friday.
Adam Byrne returns from a knee injury and will be available.
There remains no update on Jamie Heaslip.
