The first concussion occurred on January 15, 2022, in a game against the St. Louis Blues, when Muzzin was checked into the boards by Blues forward Klim Kostin. He missed seven games as a result. The second happened after a collision with Chris Wideman of the Montreal Canadiens on February 21, 2022 (his 33rd birthday). Muzzin did not return to the ice until April 2022 and played for the Leafs in the playoffs.
