O’Brien ruled out of Pro12 final

Leinster flanker Seán O’Brien, who scooped the man of the match award in last weekend’s Heineken Cup final, has been ruled out of the province’s RaboDirect PRO12 final clash against the Ospreys in the RDS on Sunday (4pm) due to a knee injury.

Leo Cullen leads a team which includes 13 Ireland internationals for the province's third meeting of the season against the Welsh side.
