In the mean time, the Bruins will take on the same approach that has served them so well throughout the season. With so many bodies in and out of the lineup because of injury over the course of the year, Boston is well versed in taking on the "Next Man Up" mentality.
"Especially this season, we had a number of those situations where we had key players out of the lineup for some time," said Zdeno Chara, McAvoy's regular defense partner. "We handled it well. It's a similar situation. We just have to respect that the league made a decision on Charlie and somebody else is going to play bigger minutes and increase the role."
That someone is likely to be either Steven Kampfer or John Moore. During Wednesday's practice at Warrior Ice Arena, it appeared that Kampfer had the edge, as he participated in normal rushes alongside Matt Grzelcyk on Boston's third pairing.
"Next man up, go and do your job and be ready for it," said Kampfer, who has suited up for one game this postseason (Game 3 against Toronto). "It's a big game and you just want to put your best foot forward…a lot of it is mental preparation. Going into it, [Carolina's] a fast team, they're gonna come hard.
"You've got to be ready for it…get a hit your first shift or move your feet and make a play. That's pretty much all you're looking for."
Moore has not played since Game 7 of the first round against the Maple Leafs as he deals with an upper-body injury. Bruins general manager Don Sweeney indicated on Tuesday that Moore may not be 100 percent, but is available to play if needed.
"It's between [Kampfer] and John Moore, we have to make that decision," Bruins coach Bruce Cassidy said of which defenseman would replace McAvoy. "I'll let you know [Thursday morning]. If Kampfer goes in it's three righties, three lefties.
"I think you're gonna see some different combinations tomorrow depending on the circumstance."
