Back in action.

Leinster have been boosted by the return of Ireland and Lions star Sean O’Brien to full training this week ahead of a crucial period of fixtures both domestically and Europe.

The eastern province face inter-provincial rivals Connacht this weekend at the Sportsground, before hosting Munster at the Aviva Stadium on October 6th.

They then begin the defence of their European crown with back-to-back games against Dai Young’s Wasps at home and French giants Toulouse away.

O’Brien’s return means more competition for places with Josh van der Flier and Dan Leavy also making successful returns to action in recent weeks for the province.
