Bruce Cassidy Sends Big Message With Line Changes.

Boston dropped a hard fought Game 2 in double OT on the weekend and now head to Columbus with the series tied 1-1. 

Bruins' head coach Bruce Cassidy has decided to send a message with a change in his lineup. 

Cassidy has officially demoted David Pastrnak to the third line for now. 

There's no guaranteed indication that Pastrnak will start on the third line for Game 3, but the Bruins' sniper has clearly struggled and the second round of the playoffs isn't the time to have mental blocks. 

Here's a look at Cassidy's lineup at practice:

Marchand-Bergeron-Heinen
DeBrusk-Krejci-Kuhlman
Johansson-Coyle-Pastrnak
Nordstrom-Kuraly-Acciari

Chara-McAvoy
Krug-Carlo
Grzelcyk-Clifton
