There appears to be a mounting belief that Chicago Blackhawks goaltender Corey Crawford could be sidelined for the remainder of the season, reports Mark Lazerus of the Sun-Times.

Head coach Joel Quenneville said 10 days ago that Crawford was expected to return from an upper-body injury at some point, but apparently it's not quite that cut and dry.

From Lazerus:

Three sources told the Sun-Times that Crawford is dealing with vertigo-like symptoms, for the second time in his career. And there is a growing concern within the organization that Crawford could miss the rest of the season, Sportsnet’s Elliotte Friedman reported on Tuesday.

Crawford has not played since Dec. 23, and was placed on injured reserve shortly after the holiday break, at which point he was ruled out indefinitely.

Prior to being removed from the lineup, Crawford was playing some of the best hockey of his career, posting a record of 16-9-2 with a .929 save percentage. Anton Forsberg and Jeff Glass have been tending the net in his absence, and the Blackhawks currently sit bottom of the Central Division standings.

Crawford missed almost a month at the end of 2015-16 with what was reported to be symptoms of vertigo, but he was able to return for the postseason.
