The Toronto Maple Leafs will be without Chris Tanev for at least one week.
The defenceman has been placed on injured reserve, according to the NHL roster page.
Tanev exited Saturday's win over the Colorado Avalanche halfway through the first period with an upper-body injury.
The 36-year-old skated off in visible discomfort after a collision with Avalanche forward Artturi Lehkonen in front of the Maple Leafs' net.
Tanev has one assist over Toronto's first six games while averaging 16:51 of ice time per contest.
The veteran blue liner was limited to just 11 games last season by multiple injuries and underwent season-ending core muscle surgery in March.
The Maple Leafs recalled Marshall Rifai from the Toronto Marlies in a corresponding move. He's been held pointless through three games in the AHL this season.
Rifai has just three games of NHL experience, all with the Maple Leafs.
