The Boston Bruins got a bit of a scare on Sunday night when Matt Grzelcyk left the game and didn't return. 

Head coach Bruce Cassidy gave an update regarding the defenseman and it seems to be pretty positive. 

Cassidy said that Grzelcyk's X-rays were negative and the defenseman "may have dodged a bullet".

The B's defenseman was hit in the right arm by Patrick Hornqvist while fighting for the puck. It looked like his right arm was injured after it was pinned against the boards during the hit and had to be helped off the ice. 

We should expect a more detailed update sometime today.
