Jake Muzzin has been diagnosed with a concussion and will miss the next two games.
"Yesterday after practice, he reported that he wasn't feeling quite right," Maple Leafs coach Sheldon Keefe said Tuesday. "He took that hit in the game ... (a 6-5 win against the St. Louis Blues on Saturday). They were monitoring him for that but he felt he was OK to practice. Due to the intensity of practice, he wasn't liking how he was feeling. At this point, he's been diagnosed with a concussion so he's not going to travel with us and won't be available this week."
Muzzin took a hit along the end boards from Blues forward Klim Kostin at 3:30 of the second period Saturday but finished the game.
"It rocked me kind of pretty good a little bit, so it definitely kind of startled me the rest of that shift, that's for sure," Muzzin said after practicing Monday.
With Muzzin unavailable, Rasmus Sandin skated with
Alex Biega
and Travis Dermott skated with Timothy Liljegren at practice. Morgan Rielly remained on a pair with TJ Brodie.
The Maple Leafs visit the New York Rangers on Wednesday (7 p.m. ET; TNT, SN, TVAS, NHL LIVE) and the New York Islanders on Saturday.
Muzzin scored 11 points (one goal, 10 assists) in 35 games this season. -- Dave McCarthy
