The Boston Bruins will try and keep their lead going on the Tampa Bay Lightning for first place in the Atlantic Division. 

It'll be an interesting test for the Bruins as they play the red hot Philadelphia Flyers who have won nine games in a row. 

Unfortunately for the Bruins, as announced yesterday they'll be without two of their best defensemen. 

Both Torey Krug and Brandon Carlo will be out of the lineup tonight. 

It'll be an interesting blueline as the only defensive pairing that looks normal is Zdeno Chara and Charlie McAvoy. 

Tuukka Rask gets the start for the B's and he'll go up against young phenom Carter Hart of the Flyers. 

Here's a look at tonight's full projected lineup:

Marchand - Bergeron - Pastrnak
Ritchie - Krejci - Kase
Kuraly - Coyle - DeBrusk
Nordstrom - Lindholm - Wagner

Chara - McAvoy
Grzelcyk - Lauzon
Moore - Clifton
