Muzzin sustained the injury during the second period on a non-contact play. While skating through the neutral zone, he stopped mid-stride, appearing to be in discomfort. He skated to the bench, headed to the dressing room and did not return.
After the game, which Montreal ended up winning 3-2 in overtime to force a Game 7, Maple Leafs head coach Sheldon Keefe did not yet have an update on Muzzin’s status.
Muzzin had four goals and 23 assists in 53 regular-season games this year.
