Irish international Seán O’Brien ends a three-month injury lay-off when he starts at openside flanker for London Irish in Saturday's Gallagher Premiership first round trip to Worcester.

O'Brien, a former British and Irish Lion, has endured a miserable spell since his move to England and missed much of last season with a hip injury.
