BOSTON —  Boston Bruins defenseman Johnny Boychuk is expected to miss roughly four weeks because of a broken arm.

Boychuk sustained a slight fracture of a bone in his left forearm in the first period of the Bruins’ 3-2 loss to the New York Rangers on Saturday.

Boychuk, who signed a two-year contract extension in June, has three assists this season. The 6-foot-2, 225-pound Boychuk had five goals and 10 assists in 51 games last year.


KINGS: Los Angeles put star defenseman Drew Doughty on injured reserve while he recovers from an apparent concussion.

Doughty, 20, was hurt last Wednesday on a hit by Carolina’s Erik Cole, who ran into him in the neutral zone well after Doughty passed the puck. The NHL declined to penalize Cole for the hit, ruling it occurred during normal play.

The 2010 Norris Trophy finalist is eligible to return Thursday in Dallas, but the Kings don’t expect him back before Saturday, when they return from a five-game trip to host New Jersey.


CANUCKS: Rick Rypien has apologized for grabbing a fan during a game last week.

Rypien, a forward, is serving a six-game suspension for making contact with James Engquist during a game against the Minnesota Wild in St. Paul on Oct. 19.

“I know what I did was wrong,” Rypien said.

Rypien was headed to the locker room after being assessed a double minor for roughing and 10-minute misconduct when he reached up and grabbed Engquist, a fan applauding at the railing. Rypien was pulled away by teammate Manny Malhotra and coach Alain Vigneault. Engquist and his brother, Peter, were removed from the area.

“It’s not my character to do stuff like that,” said Rypien. “I don’t think I can see myself doing something like that again.”


THRASHERS: Atlanta activated goalie Ondrej Pavelec, less than three weeks after he collapsed in the season opener.

Extensive testing determined that Pavelec’s initial problem was merely a common type of fainting spell. He collapsed just 2:25 into the Oct. 8 opener against Washington, falling backward onto the ice and striking his head, causing a concussion.


BLUES: Defenseman Roman Polak will miss at least one game with a laceration on his right wrist.


BLUE JACKETS: Columbus activated right wing Jared Boll off the injured list after the forward missed six games with back spasms.


PENGUINS: Pittsburgh assigned forward Eric Tangradi and defenseman Andrew Hutchinson to Wilkes-Barre/Scranton, clearing the way for forward Arron Asham to be activated for Wednesday’s game at Tampa Bay.

Asham has been out since injuring his left shoulder late in the preseason.


BLUE JACKETS 2, FLYERS 1: Kyle Wilson scored his first NHL goal and Mathieu Garon stopped 28 shots to lead Columbus past visiting Philadelphia.


CANADIENS 3, COYOTES 2: Andrei Kostitsyn’s goal 1:25 into overtime gave Montreal a win over visiting Phoenix.


KINGS 3, WILD 2: Michal Handzus scored in the fifth round of a shootout as visiting Los Angeles earned its fifth win in its last six games.

Anze Kopitar had a goal and an assist in regulation and also scored in the shootout for the Kings.
