The Blue Jackets announced Friday that they activated Jack Roslovic off injured reserve and placed Zach Werenski on IR. 

Roslovic has missed the last 21 games after suffering a fractured ankle on Nov. 12 against the Rangers. He's posted 2-6--8 in 14 games this season.

Werenski is week-to-week with an ankle injury he suffered in the second period of Wednesday's loss to the Devils. In 34 games this season, he's posted 1-24--25 while averaging 24:04 TOI/game. 

Roslovic is slated to play as the fourth-line RW when the Blue Jackets host the Maple Leafs on Friday at 7 p.m. ET on Bally Sports Ohio.
