Chicago Blackhawks goalie Corey Crawford has been out since last month with another injury surrounded by question marks. 

This time Crawford is on injured reserve because of a concussion and everybody's wondering what's going on. 

Well it doesn't sound good at all. 

“All I know is he’s in the [concussion] protocol and nothing’s changed as far as improvement,” head coach Jeremy Colliton said.

Not a good sign considering Crawford missed 47 games last year with a concussion as well.

To make it worse, Crawford admitted he was still feeling lingering effects of that concussion during training camp this year. Add that with another concussion this year and it could be a dangerous mix.

Backup Cam Ward is 2-3 with a .897 save percentage since Crawford's injury and is 6-7-4 overall this season with a 3.85 goals against average and .888 save percentage.
