Toronto forward Max Pacioretty has been ruled out for the Maple Leafs' game Monday night against the visiting Tampa Bay Lightning because of an upper-body injury.

Toronto Maple Leafs left wing Max Pacioretty (upper body) was placed on Injured Reserve on Wednesday. The move is retroactive to Jan. 18, meaning Pacioretty will not be eligible to return to the lineup until next week.

The 20-year-old centered the Maple Leafs' third line with Max Domi and Nick Robertson on his wings. Minten was recalled from the Marlies on Thursday after John Tavares went down with an injury at practice. Before Toronto's morning skate got underway, a few of the team's injured players were seen on the ice.

To fill the veteran winger’s roster spot, the Leafs called up 22-year-old forward Jacob Quillan from the Marlies, who has 15 points in 35 games. Pacioretty missed Monday’s game against Tampa Bay and was not going to play against the Blue Jackets, head coach Craig Berube said on Monday.

If Knies does miss at least Saturday in Ottawa, it could be the Leafs first look at 22-year-old Jacob Quillan the forward called up from the Marlies Wednesday morning for Pacioretty. “You never want to see a guy go down,” Matthews said of his fellow Arizonan Knies. “I didn’t see what happened (on the hit), but you’re obviously hoping for the best.”

The Toronto Maple Leafs faced a tough night on multiple fronts, suffering a 5–1 loss to the Columbus Blue Jackets on Wednesday and seeing key forward Matthew Knies exit the game with an upper-body injury. The injury occurred late in the second period when Knies delivered a hit on Blue Jackets forward Kirill Marchenko but got the worst of it.

Goaltender Dennis Hildeby was exposed against the Columbus Blue Jackets in the Leafs’ 5-1 loss at Scotiabank Arena, as his mobility in the crease was an issue as Toronto’s three-game winning streak came to an end.
