Blues' Pavel Buchnevich: In concussion protocol

Buchnevich left Tuesday's game versus the Senators after a hit to the head, and the winger has entered the concussion protocol, Jeremy Rutherford of The Athletic reports.

Buchnevich exited the contest late in the third period. Head coach Craig Berube said Buchnevich didn't appear to be laboring after the hit. The winger's status will likely be updated prior to Thursday's game versus the Rangers. He's been limited to just a single goal in his last seven outings.
