Unfortunately, the win was a sidenote to what could be a major injury situation for the Blackhawks. Jonathan Toews missed the entire third period, despite remaining on the bench for the entire frame.  Many are speculating that Toews suffered a concussion after this hit from Boston defenseman Johnny Boychuk.

Toews has a long history of concussions, but the fact that he remained on the bench could be a good sign.
