Toronto Maple Leafs captain Auston Matthews is set to miss a week of action after being placed on injured reserve Friday with a lower-body injury.
The injured reserve placement was retroactive to Tuesday, meaning he will be out through at least the following Tuesday.
The forward's status was up in the air after he exited in the second period of Tuesday's game against Boston following a hit from behind by Bruins defenseman Nikita Zadorov.
"[Matthews] may be back sooner [than a week]," coach Craig Berube said Thursday, prior to the IR move. "One of those things [where] he could come in a couple days from now feeling a lot better and hopefully he's good to go. But we'll see."
It was midway through the second period Tuesday when Matthews was knocked into the boards, and he immediately sought to retaliate on Zadorov with a hit of his own against the blue liner. Matthews didn't take another shift and left the Leafs' bench at the next TV timeout. He did not return for the third period.
There was no penalty called on the play, something Berube didn't agree with.
"I think it's a penalty, personally," he said on Tuesday. "I don't like it; I don't like the hit [from Zadorov]. [Matthews] was in a vulnerable position."
This will be Matthews' first injury-related absence of the season after he was sidelined for 15 games last year. The three-time Rocket Richard Trophy winner has nine goals and 14 points in 17 games this season.
"We played last year without [Matthews] for a while, and it's just next-man-up mentality [again]," said Berube. "Guys get a bigger bite here, a bigger role. We need a better team game."
Matthews wasn't the only one who was forced out of Tuesday's contest. Goaltender Anthony Stolarz also left after the first period, during which he allowed three goals on 10 shots. Berube said on Tuesday he didn't think Stolarz's issue was serious and declared on Thursday he was day-to-day. The netminder is 6-5-1 this season with an .884 SV% and 3.51 GAA.
Dennis Hildeby is expected to start for Toronto against the Kings. The Leafs recalled goaltender Artur Akhtyamov from the American Hockey League on Thursday to back up Hildeby. They also placed forward Scott Laughton on injured reserve with an upper-body injury.
