Bruins captain Zdeno Chara  is working his way back from an undisclosed injury, but that isn’t the biggest concern on Boston’s blue line.
That would be the season-ending ACL/MCL tear to Dennis Seidenberg , who will have surgery on his knee and should be ready to go for the start of next season. In the meantime, the B’s are down their second-best defenseman and runner-up in time on ice.
“It’s very unfortunate,” Chara told WEEI.com. “I was on the bench when it happened, and we all saw what happened, and right there I kind of knew it was a very unlucky collision. He’s such a big loss for us. He’s a [guy] who’s playing in all situations, logging a lot of minutes. He’s a true warrior. To lose a guy like that always hurts, but it’s something that we’re going to have to play through. Obviously it’s going to be a chance for other guys to step up and fill that role.”
Seidenberg’s injury means that Chara will have a new postseason defense partner for the first time in a long time. Paired together from Game 3 of the 2011 Eastern Conference quarterfinals and onward, Chara and Seidenberg have teamed to make up a formidable top pairing that has shut down the top lines of some of the most offensively loaded teams in the NHL  on the way to two Stanley Cup  finals appearances.
Likely candidates to replace Seidenberg as Chara’s postseason partner would appear to be Dougie Hamilton and Johnny Boychuk , both of whom have played plenty alongside Chara during the regular season. Yet Chara isn’t looking that far ahead. After all, Chara himself and Hamilton both need to get healthy before the Bruins’ back end can begin to look like its usual self.
“I mean, we’ll see,” Chara said. “We’re far from the playoffs this time of the year. Right now we’re just really trying to focus on getting guys back, which will hopefully be soon. When we get a full lineup, then we’re going to be feeling what the ice times and positions are going to be like. But we’re obviously trying to get through tougher times right now with the injuries we have.”
Chara practiced for part of Monday’s session, with Claude Julien  telling reporters on hand that his status for Tuesday’s game against the Islanders has yet to be determined.
