The Chicago Blackhawks and general manager Stan Bowman announced some roster moves and injury news on Wednesday. 

Forward Marcus Kruger has been placed on injured reserve because of a concussion. 

Kruger took a big elbow from Ryan Hartman and left the ice bleeding. 

Kruger joins goalie Corey Crawford who's currently also on the IR with a concussion. 

The team also announced they've called up Luke Johnson from the AHL to replace Kruger on the roster.

Kruger will be eligible to return to action December 27th at the earliest.
