Liles (concussion) is showing on injured reserve, per the NHL's official media site.

EDGE Analysis

For obvious reasons, the B's need to protect Liles' noggin, but especially so because he's regarded as one of the smartest blueliners in the game. With towering defenseman Zdeno Chara (lower body) also injured, it might be in the best interest of the Bruins to summon a rearguard from the minors -- currently, the team only has six healthy skaters available on the back line.
