Lines, roster updates and starting goaltenders ahead of Boston-Chicago game

After suiting up in Monday's OT loss to the Kings, defenseman Jack Achan will remain in the lineup, sliding in on Boston's second pairing alongside Brandon Carlo.

Head Coach Bruce Cassidy revealed this afternoon that Achan is once again filling in for Matthew Grzelcyk, who was supposed to make to his comeback from an upper-body injury, but will be held out due to an illness instead.

Perhaps the biggest switch the B's bench boss announced is the one he'll be making between the pipes however.

Red-hot Jeremy Swayman is taking over for Linus Ullmark, and the rookie netminder will once again be looking to showcase his elite skills.

Here are the Bruins' projected lines for tonight:

Brad Marchand – Patrice Bergeron- Jake Debrusk
Taylor Hall – Erik Haula – David Pastrnak
Trent Frederic – Charlie Coyle – Craig Smith
Nick Foligno – Tomas Nosek – Curtis Lazar

Mike Reilly – Charlie McAvoy
Jack Ahcan – Brandon Carlo
Derek Forbort – Connor Clifton

Chicago will be starting goaltender Kevin Lankinen in front of their net for tonight's matchup. The initial puck drop for the Bruins-Blackhawks game is scheduled for 7p.m. ET at Boston's TD Garden.
