Ireland pulled clear of hosts Canada with four tries in the closing half hour as they earned a 40-14 victory at the BMO Stadium on Saturday night. Check out some photos from the Toronto tussle.
Commenting on the injury, Leinster head coach Joe Schmidt said: "Obviously to lose a player of Luke's pedigree at such a crucial time of the season is a massive blow, not just for the team and our supporters but also for the player himself.
"Luke has been in fine form recently and as well as his capabilities on the field, he is a positive and popular presence within the dressing room.
"Knowing Luke, he will be determined to overcome this setback and aggressively tackle his rehab to regain full fitness and he will continue to benefit from the full support of Leinster Rugby and the IRFU during that time frame."
