Here is the Bruins' projected lineup for their game against the Senators.

The Boston Bruins are playing the Ottawa Senators this afternoon in a very important contest. The Bruins are only ahead of the Senators by one point for the final wild card spot in the Eastern Conference, so a win is much-needed.

The Bruins will have one change in their lineup against the Senators. After suffering an upper-body injury against the Tampa Bay Lightning last game, forward Cole Koepke won't be in the lineup. 

Koepke's replacement will be determined shortly. Bruins head coach Joe Sacco said forward Mark Kastelic would be back in the lineup if he is given the green light to play by the medical team. If not, Oliver Wahlstrom will replace Koepke in the lineup.

On the blueline, Bruins star Charlie McAvoy will not play as he continues to work through his injury. With this, Brandon Carlo will be his replacement on the top pairing.

Here is the Bruins' full projected lineup now.
