Recovering O’Brien in the frame for Leinster

Ireland and Lions back rower O’Brien returned to action last weekend after more than five months on the sidelines, having injured his shoulder against Ulster in December, causing him to miss the entire Six Nations campaign.
O’Brien came through his 52-minute stint in Saturday’s game against Edinburgh unscathed and has trained well so far this week with no adverse reaction, putting him in the frame to feature against Ulster this weekend.
