Leinster Rugby back-row forward Sean O’Brien, who broke his right arm playing for Ireland against Argentina on Saturday, is expected to return to action before the end of the Pool stage of the Heineken Champions Cup.

Ireland head coach Joe Schmidt reckons that the 31-year-old’s “ability to bounce back” and “resilience” will “give him a chance of getting back towards the end of the year”.

Leinster’s last two Pool matches in this season’s Champions Cup take place on January 12, when they entertain Toulouse, and January 20, when they travel to Wasps.

O’Brien missed all but two games of Leinster’s Champions Cup-winning campaign last season, when they won the trophy for a record-equalling fourth time.

However, this season the British and Irish Lion has featured in Leinster’s 52-3 home rout of Wasps on the opening night of the Champions Cup and in their dramatic 28-27 loss at Toulouse in Round 2 last month.

He is a three-time winner of the European Cup – in 2009, 2011 and 2012 – and has also picked up a Challenge Cup winners’ medal, in 2013.
