Dougie Hamilton out of Bruins lineup indefinitely with injury

First, the Boston Bruins lost their hold on a playoff spot, and now they’re minus their top-scoring defenceman.

Third-year blue-liner Dougie Hamilton will be sidelined indefinitely with an undisclosed injury and evaluated in a few days, according to head coach Claude Julien.

Hamilton, 21, may have suffered a shoulder injury during Boston’s 2-1 shootout loss to Florida on Saturday. He didn’t play after the 19:23 mark of the second period after being hit against the boards by Panthers forwards Scottie Upshall and Nick Bjugstad.

Hamilton tops the Bruins defence with 42 points on 10 goals and 32 assists and is second to Patrice Bergeron (51 points) in team scoring this season.

He’s also averaging 21 minutes 20 seconds of ice time per game and tops all Boston rearguards this season in power-play goals (five) power-play points (15), game-winning goals (two) and shots on goal (188).

Zach Trotman has been recalled from the team’s American Hockey League affiliate in Providence and partnered with Matt Bartkowski on the blue-line for Tuesday’s practice.

Trotman has played 18 games with the parent Bruins, collecting four assists. The 24-year-old’s two-year contract becomes a one-way deal next season, so he could treat the next three weeks as an audition.

Boston, which sits one point back of Ottawa for the second wild-card playoff spot in the NHL’s Eastern Conference, is in a 0-3-2 funk in which it has allowed 15 goals.

“The Senators are playing well,” Bruins forward Milan Lucic told reporters Tuesday. “We just have to make sure to focus on ourselves and take care of our business. That will give us the best chance to get back in the playoff picture.”

The Bruins are also without forward David Krejci, who has missed 15 games with a partial ligament tear in his left knee, but he could return for Thursday’s matchup against Anaheim.

“We just have to come together as a team and find ways to win hockey games,” Lucic said. “We’ve shown throughout this season that when we put our minds to it and want to play the game plan, we can have success.”

In other injury news, Bruins forward Dan Paille practised Tuesday with a full shield after he took a puck to the mouth in Sunday’s 5-3 loss to Tampa Bay.
