Head Coach Claude Julien gave the update on Bergeron following the team's optional skate on Saturday morning at the ACC.
Tuukka Rask was back on the ice to take part in the optional after being given a maintenance day on Friday. He was the first netminder off the ice at pregame skate, indicating he could be the starter against Toronto.
Anton Khudobin stayed on the ice for extra work. Julien has suggested that he doesn't want Khudobin sitting for too long without a start, to keep both goaltenders in a groove.
Though the Bruins held an optional on Saturday, the lineup can be expected to be the same as Thursday's opener in Columbus. (See below for projected lines and pairings.)
Boston was able to spoil the Blue Jackets' home opener on Thursday, and will hope to do the same in Toronto for their first divisional matchup of the season.
The ACC will certainly be rocking, especially with the Leafs kicking the night off with a pregame ceremony for their 100th Anniversary season (puck drop slated or 7:18 p.m. as a result), and this year's No. 1 overall pick Auston Matthews leading a young, up-and-coming team.
"Well, obviously it's a special night here for Toronto. They're celebrating their 100th Anniversary and a lot of things going on, and I'm sure they're team is going to be ready to follow up here with a good performance," said Julien.
"The biggest thing is you really focus on your team and what you need to do here to win. They're a young team that have a lot of team speed, and they're certainly a team that plays it tight, so we have to make sure that we're on our game and that we respect their strengths and hopefully be the better team by the end of the night."
The Bruins overcame a two-goal deficit to score five unanswered goals on Thursday night, but they're hoping to tighten up their game from the get-go.
"They play with a lot of skill. They've got some really talented forward, so we've got to play smart," said Brad Marchand, who was all business again on Saturday morning, and not feeding into the hype of World Cup carryover and his five-point game on Thursday.
"We can't play sloppy, and we just have to play and believe in our system."
