Sean O'Brien ruled out as Leo Cullen names his team for Champions Cup semi-final against Clermont
Sean O'Brien has been ruled out of Leinster's Champions Cup semi-final against Clermont this Sunday (kick off 3pm) in Lyon.
O'Brien is the only enforced absentee with a tight hamstring and will be assessed early next week ahead of the Pro12 clash against Glasgow Warriors.
Isa Nacewa will once again captain Leo Cullen's men in what will be his 50th cap for the Blues. Nacewa starts on the left wing with Fergus McFadden coming into the side on the right wing for his 150th Leinster appearance.
In the centre Robbie Henshaw and Garry Ringrose renew their partnership with Luke McGrath and Johnny Sexton in the half backs. Sexton reached the 1,200 point mark for Leinster against Wasps with his 12 points from the boot.
The front row is again the all Irish international trio of Jack McGrath, Richardt Strauss and Tadhg Furlong.
In the second row Devin Toner and Hayden Triggs continue their partnership.
Finally in the back row Rhys Ruddock comes in at blind side flanker, with Dan Leavy moving across to the open side and Jack Conan continuing at number eight.
On the bench there is a welcome return to European action for Seán Cronin, while Peter Dooley is in line to make his first European appearance of the season should he be introduced.
Meanwhile, Conor Murray as been ruled out of Munster's clash with Saracens tomorrow.
