O’Driscoll returns for Leinster
The Irish captain suffered a knee injury during the European quarter-final win against Clermont last Friday week while Reddan was pulled from the side which defeated the Ospreys last weekend with a quad strain.
Both are part of a very strong Leinster selection for the rescheduled tie with Michael Bradley’s men while Leo Cullen, Cian Healy and Jamie Heaslip are all named on a noteworthy bench.
