The Edmonton Oilers will be without defenseman Duncan Keith and winger Zack Kassian for a while.

Keith could be sidelined for two to four weeks due to upper-body soreness and concussion protocol, while Kassian will be out for four to eight weeks with a fractured jaw, the team announced Thursday.

Keith crashed hard into the boards during the first period of Wednesday night's contest against the Chicago Blackhawks and needed assistance to get off the ice. The Oilers ruled him out for the rest of the game shortly after. The 38-year-old has registered 14 points in 35 contests this season while averaging just over 20 minutes a game.

Kassian also exited Wednesday's matchup with an injury after taking a puck to the face in the second period. He has five goals and nine assists in 35 games this campaign.

The Oilers currently sit fifth in the Pacific Division with a 23-18-3 record.
