The Boston Bruins were back on the ice for practice on Monday morning after a crazy weekend. 

Unfortunately they were without two key defensemen. 

Both Brandon Carlo and Torey Krug were missing from practice and both will be forced to miss tomorrow's game against the Flyers in Philly. 

Jeremy Lauzon and Connor Clifton stepped in to fill the holes. 

Here's a look at today's lines from practice:

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

Chara - McAvoy
Moore - Lauzon
Grzelcyk - Clifton
