The Bruins got both Jaromir Jagr and a win over Ottawa on Tuesday, but it still might end up being a shaky day for them as Patrice Bergeron  was knocked out of the game in the second period against the Senators.
The B’s got goals from David Krejci , Tyler Seguin  and Nathan Horton  in a 3-2 victory that put them one point behind the Canadiens in the Northeast Division. The Habs have 51 points to the Bruins’ 50 through 35 games.
Here’s what went right and wrong for the B’s:
WHAT WENT RIGHT FOR THE BRUINS
– Horton is producing like a man who has no interest in losing his spot on the top line to Jagr. He broke a third-period 2-2 tie by scoring his fourth goal in as many games after scoring just once in the previous 14 contests. The veteran right wing has been inconsistent this season, but he’s really making that top line a tough one to break up.
– Give Matt Bartkowski credit for staying focused and turning in some solid play despite knowing that the Bruins tried to trade him for Jarome Iginla. Bartkowski saved a goal in the second period, when Khudobin made a kicksave on Mika Zibanejad and kicked the rebound out to the bottom for the right circle. A Senators player was inches from knocking it in with plenty of open net, but Bartkowski got a stick on it just in time to break it up.
WHAT WENT WRONG FOR THE BRUINS
– Bergeron was knocked out of the game on his third shift of the second period with what appeared to at the very least be some sort of upper-body injury. Bergeron lunged at Colin Greening while the Washington center was trying to shoot, and Bergeron’s head awkwardly hit Greening’s elbow/forearm. Bergeron left the game and did not return.
Though the Bruins offered no details on the injury, the play was obviously concerning given his history with concussions. He has had three in his NHL  career, the most recent of which came in Game 4 of the Eastern Conference semifinals against the Flyers in 2011.
Bergeron leads the Bruins with 31 points (10 goals and a team-high 21 assists) this season.
– The Bergeron injury wasn’t the only one for the Bruins. Dougie Hamilton threw a hit on Erik Condra in the Bruins’ zone, and though the play got a massive cheer as both players went down, Hamilton couldn’t finish his shift. Upon getting up, he slowly tried to get in position before calling for a line change. He went straight down the tunnel and left the ice for about 10 minutes real time before returning to the Bruins’ bench with five and a half minutes to play.
– The Bruins appeared to get the save of the year from Anton Khudobin when he lost his stick diving across the net to stop a bid from Andre Benoit after being out of position. The play was reviewed, however, and the replay showed that Benoit’s slapshot had indeed gone in and bounced back out.
– Benoit’s goal tied the game at two, making for the Bruins’ latest blown lead in the third period this season. Boston has now blown leads in seven games this season and are 4-3-2 when leading after two periods.
