Marchand sustained an upper-body injury in a 5-2 loss to the New Jersey Devils on Thursday. However, coach Bruce Cassidy said Marchand and defenseman Charlie McAvoy, who's on injured reserve, will travel with the Bruins to the Bridgestone NHL Winter Classic in South Bend, Indiana, and could play against the Chicago Blackhawks at Notre Dame Stadium on Jan. 1 (1 p.m. ET; NBC, SN, TVAS).
Boston has lost two straight after a three-game winning streak. The Bruins have allowed at least three goals in nine of their past 13 games.
Buffalo forward Jason Pominville returns after missing three games with an undisclosed injury sustained in a collision with teammate Rasmus Ristolainen on Dec. 18 against the Florida Panthers. The Sabres are 1-3-0 in their past four games and have scored two goals or fewer in three of those games.

They said it

"Whoever's out there needs to do a better job than last game, and part of that's on the forwards. … [It] has to be a shared responsibility with whichever forward line is out there." -- Bruins coach Bruce Cassidy on defending against Sabres forwards Jack Eichel and Jeff Skinner
"Our next handful of games are against teams that are right there with us. You want to make sure you push them back. But the biggest thing for us is worrying about our game and getting back to playing the way we know we're capable of and playing the way that led to us having success." -- Sabres forward Jason Pominville
