Leinster have been handed a boost ahead of their Champions Cup clash with Montpellier at the RDS tomorrow with the news that captain Isa Nacewa will start.

Nacewa had been a doubt with a calf injury but he has now recovered and will lead Leinster against the French side from the centre.

However, Sean O'Brien has not sufficiently recovered from his own calf injury and misses out while Ireland international out-half Johnny Sexton has failed to shake off a dead leg.

Otherwise, it's the same back three that took to the field in the win over Munster with Joey Carbery lining out at full-back for the fifth time in seven games this season.

Adam Byrne is also lining out for his fifth start this term on the right wing and Barry Daly is selected on the left for his European debut. 

In the half backs, Luke McGrath is again selected at scrum half with Ross Byrne starting at out-half for Sexton.

There are no changes among the pack with Jack McGrath, James Tracy and Tadhg Furlong in the front row and Devin Toner and Scott Fardy behind them in the second row.

Rhys Ruddock, Josh van der Flier and Jack Conan complete the starting XV.

Leinster: Joey Carbery; Adam Byrne, Robbie Henshaw, Isa Nacewa (capt), Barry Daly; Ross Byrne, Luke McGrath; Jack McGrath, James Tracy, Tadhg Furlong; Devin Toner; Scott Fardy; Rhys Ruddock, Josh van der Flier, Jack Conan.
