Toronto Maple Leaves captain auston matthews He is day to day with an upper body injury and will not be available for Tuesday’s game against the Boston Bruins.

Matthews played in Sunday’s 2-1 loss to the Wild Minnesotarecording an assist in 22:12 minutes of ice time.

Maple Leafs head coach Craig Berube revealed after Tuesday’s skate that Matthews has been playing despite a nagging injury.

“Everyone needs to do their job,” Berube said of playing without Matthews. “I don’t think you focus on, ‘Oh, Auston’s not playing, what are we going to do?’ We have a good team, good players. People will have a slightly different view on situations, lines and things like that.

“You just have to go play.”

The 27-year-old forward has spent the season as a centre-back in a line with Mitch Marner and Matthew Knies. Max Domi took Matthews’ place on that line in the game day skate.

The second line of Max Pacioretty, John Tavares and William Nylander remained intact, while Pontus Holmberg worked in the middle of a third line with Bobby McMann and Nick Robertson. Steven Lorentz, David Kampf and Ryan Reaves made up the fourth line.

“We have guys that are going to have to step up,” Domi said. “Auston is a very important part of our team, but that’s the way it is. You won’t have your full lineup for all 82 (games).”

“He can play all over the lineup,” Marner said of Domi. “Very elusive, very fast… makes a lot of great plays, very responsible with the puck.”

Anthony Stolarz worked in the home net during the session, suggesting he will make a second straight start for Toronto.

Matthews has five goals and 11 points in 13 games this season. He led the NHL with 69 goals last season and scored 107 points in 81 games.

He has appeared in all 82 games in a season only once in his career: as a rookie in 2016-17.

The first overall pick in the 2016 draft has 373 goals and 660 points in 575 career games. He is the highest-paid player in the league this season, with a cap hit of $13.25 million in the first of a four-year extension signed in 2023.

The Maple Leafs are 6-5-2 this season and are third in the Atlantic Division. The Bruins are right behind them with a 6-6-1 record.

“Great test against a good team,” Domi said. “We owe them.”
