The Calgary Flames beat the Boston Bruins on Wednesday night. But the win was somewhat marred by some uncertainty surrounding Johnny Gaudreau’s status.

Gaudreau was walloped by Bruins defender Charlie McAvoy in the third period.

Gaudreau played one shift on the ensuing power play, then was pulled from the bench. Following the game, head coach Bill Peters told the assembled media that the NHL’s concussion spotters pulled Gaudreau for an evaluation.

The Flames are off tomorrow and Peters didn’t have any updates on Gaudreau’s condition following the game, so the earliest there will be any information on his status will be at Friday’s morning skate.
