The injury may have come on a hit to Islanders' John Tavares between the circles, in front of Boston goaltender Niklas Svedberg. TSN was the first to report that the injury was to Chara's knee.
The Bruins' leader had 2 goals and 1 assists in 9 games this season, and averaged 21 minutes of ice time. This injury leaves a big hole for the struggling Boston Bruins, who are now 4-5-0 on the season. Boston is already without Kevan Miller, who is out indefinitely with dislocated right shoulder. They will now be without their captain until at least December.
