The Bruins are actually doing lines in their morning skate! Here they are, per the Bruins twitter account:
David Pastrnak is a game time decision, but it doesn't look likely:
Julien said he doesn't think David Pastrnak will be playing tonight (he skated this morning; was out last game w/ an upper-body injury)— Boston Bruins (@NHLBruins) January 15, 2016
No word on defensive pairings, so they're likely to remain similar to last game.
