Johnny Sexton is on course for a return from day one of Ireland's Rugby World Cup preparations in June.
Sexton, 37, suffered a groin injury in the final game of this year's Six Nations, the Grand Slam clinching victory over England on March 18, and had a procedure to repair the damage before the end of that month.
The Ireland skipper had hoped to return in time to play one final game for Leinster if they got to the URC final on May 27 but that ambition was ruled out by his surgeon.
