Jake Muzzin was placed on long-term injured reserve by the Maple Leafs on Thursday.
The defenseman left a 5-2 loss to the Montreal Canadiens on Monday after colliding with Montreal defenseman Chris Wideman. Muzzin did not play in a 4-3 overtime loss to the Columbus Blue Jackets on Tuesday.
Muzzin missed seven games this season because of a concussion. He scored 12 points (two goals, 10 assists) in 41 games.
"Well, he has a concussion, and in terms of the [long-term injured reserve], it's not a decision that's on my plate, but when we looked at it, it's the second situation like this in a short amount of time, and the last one, it took a few weeks before he felt comfortable playing in games," Maple Leafs coach Sheldon Keefe said ."So I think it's something I know [the medical staff] is going to want to be patient with Jake in particular given what he's been through the last little while, so it takes away any sort of pressure for him and there's no day to day asking how he's doing and how he's feeling. It's going to be a long process to give him ample opportunity to feel as good as possible."
Defenseman Ilya Lyubushkin played his second game since he was acquired in a trade with the Arizona Coyotes on Saturday.
"[Muzzin's injury] provides a ton of opportunities for others," Keefe said. "We will try out different things. Bringing in Lyubushkin, the timing is good for us to have another defenseman come in."-- Dave McCarthy
