The Boston Bruins forward is facing discipline for roughing and high-sticking Pittsburgh Penguins goalie Tristan Jarry during a 4-2 loss at TD Garden on Tuesday.
An in-person hearing is required for any suspension that could be at least six games.
"Honestly, that's lack of discipline on Brad's part in that situation," Bruins coach Bruce Cassidy said Tuesday. "I just watched the replay at the end. It looks like some words were exchanged. … Brad's a leader on our team and he needs to control his emotions in that situation."
The incident occurred with 25 seconds remaining in the third period Tuesday. Marchand received a minor penalty for roughing and a match penalty for attempt to injure.
"I think it's just the heat of the moment," Jarry said. "I think everyone's battling hard out there, he's just trying to get the puck to the net, and I think our team did a great job. It's part of the game, and it stays on the ice."
The following grounds are being considered for supplemental discipline: roughing, high-sticking. However, the Department of Player Safety retains the right to make adjustments to the infraction upon review.
"Obviously I do believe you have to protect goaltenders in those situations," Cassidy said Wednesday. "We'd have wanted ours protected. Didn't look like there was any sort of injury. Hopefully that's factored in as well."
Marchand has been suspended seven times and fined five times since March 2011. His most recent discipline was Nov. 29, 2021, a three-game suspension for slew-footing Vancouver Canucks defenseman Oliver Ekman-Larsson.
Marchand has twice been suspended five games (Jan. 9, 2012, for clipping Vancouver Canucks defenseman Sami Salo; Jan. 24, 2018, for elbowing New Jersey Devils forward Marcus Johansson). He has forfeited more than $971,000 in salary from his previous fines and suspensions.
"We'll let the League address it first, then I'll sit down with Brad," Cassidy said. "We've had our share of sitdowns over the years. I think Brad's been doing a pretty good job for the most part with controlling his emotions."
