The Bruins got a couple of positive signs regarding their injured defensemen Saturday, with Dennis Seidenberg skating prior to practice and Wade Redden returning to practice.

Following the skate, Claude Julien told reporters that Seidenberg will not play in Game 2 of the Eastern Conference semifinals against the Rangers, while Redden will be a game-time decision. Ference has yet to skate since missing Game 6 of the first round against the Maple Leafs.

Though the Bruins struggled at points without the defensemen, they have won both games played without all three, as Seidenberg left after two minutes of Game 7 against Toronto and all three players sat out for Game 1 against the Rangers.

Dennis Seidenberg

Dennis Seidenberg, Andrew Ference and Wade Redden were all absent for the Bruins’ warmup Thursday night, meaning all three are out for Game 1 against the Rangers.

The trio of injured blueliners will be replaced by rookies Matt Bartkowski, Dougie Hamilton and Torey Krug. Bartkowski and Hamilton played two games against the Maple Leafs in the first round, while this will be the first NHL playoff game and fourth game of Krug’s NHL career.

The Bruins lineup in warmups is as follows:

Milan Lucic – David Krejci – Nathan Horton
Brad Marchand – Patrice Bergeron – Jaromir Jagr
Rich Peverley – Chris Kelly – Tyler Seguin
Daniel Paille – Gregory Campbell – Shawn Thornton

Zdeno Chara – Dougie Hamilton
Matt Bartkowski – Johnny Boychuk
Torey Krug – Adam McQuaid

Tuukka Rask

Brad Marchand

Dennis Seidenberg, Andrew Ference and Wade Redden all were missing from the Bruins’ morning skate prior to Thursday’s opening game of the Eastern Conference semifinals against the Rangers. Furthermore, left wing Brad Marchand left the ice in pain about 20 minutes into the skate following 2-on-1 drills.

With the trio of defensemen absent (all with undisclosed injuries), the lineup looked as follows prior to Marchand’s exit:

Milan Lucic – David Krejci – Nathan Horton
Brad Marchand – Patrice Bergeron – Jaromir Jagr
Rich Peverley – Chris Kelly – Tyler Seguin
Daniel Paille – Gregory Campbell – Shawn Thornton

Extra forwards: Kaspars Daugavins, Jay Pandolfo, Carl Soderberg

Zdeno Chara – Dougie Hamilton
Matt Bartkowski – Johnny Boychuk
Torey Krug – Adam McQuaid

Extra defenseman: Aaron Johnson

If Marchand is unable to play Thursday, Daugavins would be the most likely choice to replace him in the lineup. Daugavins last played in Game 1 of the Eastern Conference quarterfinals against the Maple Leafs.

Dennis Seidenberg and Andrew Ference were both absent Wednesday as the Bruins practiced at TD Garden in anticipation of the Eastern Conference semifinals against the Rangers. Defenseman Wade Redden, who missed Game 7 against the Maple Leafs with an undisclosed injury, was present but did not stay for the whole practice.

The practice featured a slight change to the lines, as Claude Julien flip-flopped right wings Tyler Seguin and Jaromir Jagr. Seguin, who had been skating on the second line with Patrice Bergeron, was moved down a line to skate with Chris Kelly and Rich Peverley, while Jagr moved up to play with Bergeron and Brad Marchand.

The lines in practice were as follows:

Milan Lucic – David Krejci – Nathan Horton
Brad Marchand – Patrice Bergeron – Jaromir Jagr
Rich Peverley – Chris Kelly – Tyler Seguin
Daniel Paille – Gregory Campbell – Shawn Thornton

Extra forwards: Kaspars Daugavins, Jay Pandolfo, Carl Soderberg

The defensemen present were Redden, Zdeno Chara, Johnny Boychuk, Adam McQuaid, Matt Bartkowski, Dougie Hamilton, Aaron Johnson and Tory Krug. The pairings were as follows:

Chara-Hamilton
Bartkowski-Boychuk
Krug-McQuaid

Bruins defenseman Andrew Ference is out for Game 7 against the Maple Leafs, coach Claude Julien said prior to the game on Monday.

The defenseman, who was suspended for Game 2 and also missed Game 6 due to injury, was spotted with crutches and a walking boot on his left foot by The Boston Globe’s Kevin Paul Dupont on Monday.

Dougie Hamilton was inserted into the lineup in Ference’s place on Sunday, and the Bruins will have the choice between Hamilton and Matt Bartkowski on Monday.

Andrew Ference

TORONTO – Andrew Ference did not travel to Toronto is out for Game 6 against the Maple Leafs with an undisclosed injury, Claude Julien said following the team’s morning skate Sunday at Air Canada Centre.

Wade Redden, who missed Game 5 due to injury but practiced Saturday, was on the ice for Sunday’s morning skate and is a game-time decision for Game 6.

The injury statuses of Ference and Redden leave the Bruins in a tight spot, as both players are left-handed shots. Matt Bartkowski should be expected to play in place of Ference, but if Redden is out the Bruins will have to choose between Dougie Hamilton (a righty) and Aaron Johnson (a lefty who hasn’t played since March 30). Putting Hamilton into the lineup in place of a lefty in Ference proved troublesome in Game 2, as the B’s had to break up the Zdeno Chara-Dennis Seidenberg (both lefties) pairing in order to avoid playing Hamilton in an unfamiliar spot.

If Redden is able to play, it’s likely he would skate with Johnny Boychuk on Boston’s second pairing, while Bartkowski would man the left side of the third pairing with Adam McQuaid. If Hamilton has to play, the B’s will not only have to break up the top pairing but also have two inexperienced youngsters on their back end.

In a game when your offense isn’t finishing, every mistake is magnified. And in a playoff game, that magnification can become enormous.

Andrew Ference knows this only too well.

The Bruins defenseman mishandled a puck at the right point in the Bruins offensive end while on the power player and it led to Tyler Bozak scoring just the second shorthanded goal of the season for Toronto. Tyler Bozak won a footrace with Ference, who tried desperately to get back but couldn’t as Bozak broke a scoreless tie and the Maple Leafs held on for a 2-1 win in Game 5 Friday night at TD Garden.

“Well, it sucks,” Ference said. “It sucks to mishandle a puck, but it’s not a bad decision or anything like that. It just happens, so it’s fine. It’s happened to all of us and you deal with it.”

Now the Bruins must hit the road for Game 6 in Toronto Sunday night at Air Canada Centre.

“I can’t really recall anything ever being easy for any team,” Ference said. “Like I said, wins are difficult to get this time of year and they have to be earned. Like I said, if you don’t match a team at the beginning of a game like that, you spot them a couple of goals, it’s a tough win this time of year.”

Ference was playing with Johnny Boychuk on defense the entire game while Matt Bartkowski replaced the injured Wade Redden on defense.

“It’s tough to miss anybody, but there’s always people to come in and play well and fill a role that they need to fill,” Ference said. “Every team has to deal with that. There’s guys that go down for every single team, so there’s no feeling sorry for yourself or wishing you had a guy. You just deal with it.”

Did the Bruins miss Redden’s offense on D?

“Well, of course, but he wasn’t able to play so you don’t get into the ‘we wish this.’ It’s not the way it is,” Ference said.
