Toronto Maple Leafs forward Max Pacioretty is considered week-to-week with a lower-body injury and was placed on injured reserve Monday, the team announced.

TSN reported Monday that Pacioretty will be sidelined "for a while."

Pacioretty, 35, sustained the injury in the first period of Saturday's game against the Montreal Canadiens. He grabbed his left thigh after taking a cross-check to the back from Habs defenseman Mike Matheson. Pacioretty had to be helped off the ice and to the locker room.

Pacioretty has six points (two goals, four assists) in 13 games this season, his first in Toronto.

He has 674 points (332 goals, 342 assists) across 17 seasons with five teams, most notably the Canadiens from 2008 to 2018. Montreal drafted him in the first round in 2007.

The Leafs also announced that forwards Max Domi and William Nylander were absent from practice Monday due to maintenance.
