The Toronto Maple Leafs moved Jake Muzzin to long-term injured reserve Wednesday, according to CapFriendly.
The defenseman must miss 10 games and 24 days, during which time the club can acquire players up to a maximum of his $5.625-million cap hit.
Muzzin exited during the second period of the Maple Leafs' loss to the Montreal Canadiens on Monday after inadvertently colliding with opposing blue-liner Chris Wideman.
The Leafs held Muzzin out for the remainder of that contest as a precaution, and he stayed in Montreal overnight for observation and testing.
He then missed Tuesday's defeat against the Columbus Blue Jackets. Before that matchup, Toronto head coach Sheldon Keefe said Muzzin was back home in concussion protocol and that the 33-year-old had a "positive day."
Muzzin missed seven games earlier this season after sustaining a concussion in January, and he returned on Feb. 10.
The veteran is in his third full campaign with the Maple Leafs, who acquired him in a trade with the Los Angeles Kings in 2018-19. Muzzin has collected 12 points while averaging 21 minutes of ice time over 41 contests in 2021-22.
