"There's nothing new to report," said head coach Bruce Cassidy, per
NBC Sports Boston. "He'll be evaluated [Monday] afternoon. He will not play tomorrow [vs. Detroit] and we'll go from there.
"You don't want to go through your whole lineup and start losing good players every night, but teams go through certain stretches [with injuries] and we're no different right now with [Patrice] Bergeron and McAvoy. If Tuukka [Rask, who also missed practice Monday] is extended, then that's three important positions and three key guys. But we feel like we have the depth as long as we get [those injured players] back in a reasonable amount of time. On the back end with Charlie, this is new. We missed him for a block earlier this year and we survived it. But we'll see what happens going forward with him and how extensive his injury will be. Until we know that, it's hard to get anxious. But we also know that we have [Matt] Grzelcyk and [Adam] McQuaid that sat out last game, and are very capable defensemen."
