Ahead of Sunday's game in Pittsburgh, the Leafs placed the veteran defenceman on injured reserve, retroactive to February 25th. Given that Tanev's placement is retroactive to the game in which he was injured, he is eligible to be activated ahead of the Leafs' visit to Vegas on Wednesday.
Dewar hasn't played since January 20th, missing the last 11 games due to an upper-body injury. In 29 games this season, the 25-year-old has registered just 3 assists and 79 hits skating primarily on the fourth line and penalty killing role.
