It's been nearly a month since Corey Crawford left the game after smacking the back of his head on the post and was put in the concussion protocol. So what's the latest on the Blackhawks star goaltender?

Well, there's good news and there's non-news.

The good news is, Crawford was seen at the United Center on Wednesday after Blackhawks morning skate and appeared to be a high spirits, smiling and saying hello to several people in the hallway. It's the second time he's publicly been seen in the building, with the first being on Dec. 23 — exactly one week after his injury. Those are both positive signs.

The non-news is, there's no update on his playing status.

"No change," coach Jeremy Colliton said. "He's in the protocol. From my perspective there's no difference."

Crawford's health is the No. 1 priority, and if and when he returns to playing hockey isn't on the forefront of anybody's minds.
