He wasn't penalized on the play, either.

Dallas Stars veteran forward Luke Glendening has been placed into concussion protocol after taking a dangerous hit to the head from Calgary's Nikita Zadorov

The incident occurred at 3:57 of the 2nd period. Glendening was skating forward to retrieve a loose puck in front of the penalty box when he was leveled by Zadorov, who made contact directly with his chin on the hit: 

Not surprisingly, Stars head coach Rick Bowness was incredulous that no penalty was called on the play, calling it a "head shot" during a commercial break interview.  

The Stars have since announced that Glendening is "questionable" to return.
