"This one was for him, obviously," Matthews said. "He's our captain, he's our leader."
Matthews scored three points (one goal, two assists) to help even the best-of-7 series at Scotiabank Arena. Game 3 is at Montreal on Monday (7 p.m. ET; NHLN, CBC, SN, TVAS).
Tavares will need at least two weeks to recover from a knee injury, in addition to the concussion the forward sustained with 9:31 remaining in the first period of Game 1 on Thursday. He was injured when he fell near the blue line after being checked by Canadiens defenseman Ben Chiarot and then was hit in the face by the left knee of forward Corey Perry.

Tavares scored 50 points (19 goals, 31 assists) in 56 games this season, third on the Maple Leafs behind Mitchell Marner (67) and Matthews (66). Matthews said they needed to man-up in the absence of Tavares, who has scored 30 points (15 goals, 15 assists) in 37 playoff games.
By doing exactly that, there was a special feeling after the game.
"It means a lot, not only for the guys in the locker room but for John himself," Matthews said. "He's such a big part of this team. He's our leader.
"When something really scary and serious goes down like it did the other night, I think the response from our group was unbelievable tonight. The guys that came in stepped up big. This was a big win to even up the series."
