The Chicago Blackhawks continues to unravel. 

Over the weekend we saw it implode off the ice as Tommy Hawk body slammed a fan and now it continues on the ice as well. 

Blackhawks goalie Corey Crawford has suffered a concussion. 

It's terrible news for Crawford who has a history of concussions and just got over vertigo.

Some have said that Crawford should lean towards retirement and even during his episode with vertigo some wondered if his career was in question. 

Time to get familiar with Cam Ward, Anton Forsberg and Collin Delia.
