The defenseman was injured blocking a shot in a 5-4 overtime win against the New Jersey Devils on Friday. He played the remainder of the game.
Muzzin, who was acquired in a trade with the Los Angeles Kings last Jan. 28, has 13 points (three goals, 10 assists) in 38 games this season.
"We missed Muzzin] greatly, don't get me wrong, in more than just what he does on the ice for us," Toronto coach Sheldon Keefe said after a 5-4 overtime loss to the New York Rangers. "He has a lot of intangibles that he brings to the locker room and to the bench, talking between whistles and all those types of things. His presence means a lot to our team, so we missed him greatly, but I thought [Martin] Marincin did well, filled in well. I don't think any of our issues that we had in the game today were the result of that."
Toronto recalled defenseman
[Timothy Liljegren
from the Toronto Marlies of the American Hockey League on Saturday.
"[We will miss] a lot of leadership, a lot of physicality," Toronto forward Auston Matthews said of Muzzin. "He's a guy that obviously has experience, he's won a Cup (with the Kings in 2013-14), he holds guys accountable in the locker room. We're going to miss him quite a bit, but it's a time for an opportunity for other guys to step up in the lineup."
Maple Leafs forward Ilya Mikheyev will be out at least three months after having surgery to repair an artery and tendons in his right wrist that were severed in the game against the Devils. He was cut by the skate blade of Devils forward Jesper Bratt at 9:20 of the third period.
Signed as a free agent by the Maple Leafs on May 6, Mikheyev has 23 points (eight goals, 15 assists) in 39 games this season, including a first-period goal Friday.
