Cassidy Confirms Game 4 Lineup.

The Boston Bruins faceoff against the Columbus Blue Jackets for Game 4 of their second round matchup. 

The game takes place in Columbus and the Columbus crowd definitely showed up in Game 3, but Boston will be trying to eliminate the crowd factor early. 

We saw head coach Bruce Cassidy switch things up at practice on Wednesday and on Thursday Cassidy confirmed his changes. 

David Pastrnak will reunite with Brad Marchand and Patrice Bergeron on the team's first line while veteran David Backes will jump back into the lineup for the first time during the second round of the 2019 Stanley Cup playoffs after making four appearances against the Toronto Maple Leafs. The 35 year old will play alongside Jake DeBrusk and David Krejci. 

Here's a look at the full lineup:
