"Nothing new to report," said Cassidy. "He's getting evaluated this afternoon and will not play tomorrow. We'll go from there."
For now, Brandon Carlo will be reunited with Zdeno Chara on Boston's top pairing. The other pairings for Monday's practice were Torey Krug with Kevan Miller and a rotation of Nick Holden, Adam McQuaid, and Matt Grzelcyk.
"We can go different directions," said Cassidy. "Carlo's an easy one to slot back in with Zee, they've played together. Krug was with Miller; Grizz has been with Miller if he goes back in. We're going to keep Holden in, he can play left or right. That's something we're gonna sort through.
"We had all seven out there working and we'll make a decision in the morning…it's not set in stone what the six are gonna be."
Carlo and Chara teamed up to form one of the league's best shutdown duos last season and played together during McAvoy's four-game absence following a heat ablation procedure earlier this year. Carlo knows that moving up to play with The Captain brings with it added responsibility.
"You're matched up against certain lines when you're with the big man, so it's an extra challenge and I look forward to challenging myself in this league," said Carlo. "Ultimately, I feel like it will help me to continue to get better overall."
"I feel comfortable with whoever I play [with]," added Chara. "We have good enough players to fill the spots. Obviously Charlie can only play like Charlie and Brandon can play only like Brandon, and so on. But whatever it is, I'm comfortable [enough] to play with him."
