ANAHEIM – Wednesday was just another day in Duckdom.

For starters, Ducks coach Randy Carlyle revealed that injured defenseman Clayton Stoner underwent abdominal surgery Dec. 21 in Philadelphia and would be sidelined four to six weeks, adding to the 19 games he has already missed.

Carlyle also said ill defenseman Sami Vatanen wouldn’t travel with the Ducks to Calgary for the start of a two-game trip to play the Flames on Thursday and the Vancouver Canucks on Friday. The Ducks recalled Brandon Montour from their AHL team in San Diego to replace Vatanen.

Montour, 22, could make his NHL debut against the Flames.

“We’ll see what the next 24 hours brings,” Carlyle said.

In addition, center Ryan Getzlaf and right wing Corey Perry skated on different lines and Rickard Rakell shifted from left wing to center during the Ducks’ 55-minute practice at Honda Center, their first true on-ice workout in three weeks, according to Carlyle.

It remains to be seen if the line changes will remain intact when the Ducks take the ice to face the Flames, who thumped them 8-3 on Dec. 4 in Calgary. Carlyle said for a second consecutive day that he liked the idea of playing Rakell center rather than wing.

As if that wasn’t enough news for one day, Getzlaf acknowledged that the Ducks weren’t getting enough from him and Perry and that they were relying a little too much on the productive second line of Andrew Cogliano, Ryan Kesler and Jakob Silfverberg.

Kesler leads the Ducks with 29 points, including 12 goals.

Getzlaf has 28 points, but has scored only four goals.

Perry has 27 points, but only seven goals.

Rakell leads the Ducks with 14 goals.

“We’ve got to score goals,” Getzlaf said of his line. “That’s our job. That’s what we’re here for. (Kesler’s line is) a line that’s playing complete hockey right now. We expect them to contribute offensively as well as defensively. Our line has to be better in the goal-scoring department.”

The news blasts followed a 3-2 overtime loss to the San Jose Sharks at Honda Center in the Ducks’ first game after a four-day Christmas break, a determined and sustained effort that Getzlaf said was among the team’s best of the season.

“That was one of the better games we’ve played in a long time,” Getzlaf said. “It was a lot better than before we went into the break. Sometimes you don’t get rewarded. When you play well, you can live with losses. We got that point and we can build on it now.”

MONTOUR UPDATE

Vatanen’s absence could mean Montour makes his much-anticipated NHL debut when the Ducks face the Flames. Montour was the Gulls’ co-leader with 21 points in 25 games after San Diego’s loss Tuesday to the Reign, the Kings’ AHL team.

The Ducks expected Montour to challenge for a spot in their lineup during training camp, but they returned him to the Gulls to start the season. He leads the AHL in shots with 113 and is tied for fourth with seven goals and tied for sixth with 21 points.

“All the reports are that he’s their best player and he’s earned the opportunity,” Carlyle said.
