Sean O'Brien is out of Leinster's semi-final clash with Clermont in Lyon on Sunday.
Head Coach Leo Cullen has confirmed the back row has a tightness in his hamstring.
Joey Carberry gets the nod at full back while Fergus Mc Fadden and Isa Nacewa are on the wings.
The back row is Rhys Ruddock, Dan Leavy and Jack Conan, meaning that Josh Van Der Flier is on the bench.
