The Boston Bruins and head coach Bruce Cassidy received some tough news on Monday morning. 

Cassidy told reporters that the team has lost a top 6 forward for the night.

Forward Craig Smith is considered day to day and will miss Game 2 before being re-evaluated before Game 3. 

"Game 3 is Thursday, gives him an extra day in between that we normally wouldn't have, so that's good," said Cassidy. "We'll see how he does. Not sure we'd skate tomorrow anyways with an extra day in between but as we get close to Game 3, I'll let you know."

Jake DeBrusk will get the promotion and jump on the second line with Taylor Hall and David Krejci while Karson Kuhlman will play for the first time since the regular season. 

Check out the full lineup below:

Brad Marchand -- Patrice Bergeron -- David Pastrnak
Taylor Hall -- David Krejci -- Jake DeBrusk
Nick Ritchie -- Charlie Coyle -- Karson Kuhlman
Sean Kuraly -- Curtis Lazar -- Chris Wagner

Matt Grzelcyk -- Charlie McAvoy
