Savard suffered a Grade 2 concussion March 7 when he was on the receiving end of a blindside hit by the Penguins' Matt Cooke. Savard missed nearly two months and finally returned to action in time for the Bruins' Eastern Conference semifinal matchup against the Philadelphia Flyers in the Stanley Cup playoffs.
Savard spoke with Bruins general manager Peter Chiarelli late this summer and informed him of his condition and symptoms. Savard is with the team and is being treated accordingly, but he won't be skating until he's cleared to play. He also met with the team's medical staff Friday, but there's no timetable on his return.
"He's in good spirits," Chiarelli said Friday. "I've talked to him and met with him again. He's anxious to get back, we're just being very cautious. We'll take it day by day.
"Anytime there's this reoccurrence there's concern, but he's a very durable guy. He's played hurt in the past. He wants to come back and we want him to be healthy."
Chiarelli said that prior to the recent symptoms, the specifics of which he did not disclose, Savard was training hard during the offseason with his personal trainer and felt fine.
"It's unfortunate," Bruins coach Claude Julien said. "Right now we're missing a real good player, a player we want to see back in our lineup. Those are things we can't control and we have to move on without him for the time being."
Bruins teammate Patrice Bergeron suffered a Grade 3 concussion and missed the majority of the 2007 season, but after he returned to the ice the next season never suffered a setback. Bergeron was quick to point out Friday morning that each concussion is different.
"To be honest, I don't know enough about Savvy's situation to comment on it," Bergeron said. "My support is there for him, I'm behind him. We just want him to feel better and get well."
With Savard out, it will give younger centers an opportunity to showcase their abilities. Boston's top pick, Tyler Seguin, will be moved from the wing to the center position, something he told the coaching staff he is comfortable with.
"He's going to start at center now," Chiarelli said. "I suspect any time missed from camp for Savvy will have to be made up from a pure conditioning [standpoint] to catch up. We'll take it day by day and we're looking at other lineups now with and without Savvy."
Savard has not worked out in the past few weeks due to his symptoms. He posted 10 goals and 23 assists for 33 points in 41 games for the Bruins last season.
"It's pretty unanimous in our group that we want him back as soon as possible," Julien said. "We know the impact that he can have on a game. We hope that it gets taken care of and that he comes back in great health soon."
