Seán O'Brien joined London Irish in December 2019 from Pro 14 side Leinster.
A former British & Irish Lion, O'Brien has made over 60 appearances for Ireland, bringing valuable experience to the London Irish ranks.
O’Brien’s start to life at London Irish was staggered due to injury and he will be looking to get out on the field on a more regular basis in the 2020/21 season.
