ANAHEIM, Calif. -- A victory that enabled the Anaheim Ducks to retain control of first place in the Pacific Division might have cost them an All-Star defenseman.

Kevin Bieksa scored his first goal in 3 1/2 months to give the Ducks a lead they would not relinquish as they rallied for a 3-1 victory over the Calgary Flames on Tuesday night at the Honda Center.

Patrick Eaves and Chris Wagner also scored for the Ducks (44-23-13), who received 26 saves from goalie John Gibson and increased their lead over the Edmonton Oilers and San Jose Sharks to four points. Anaheim and San Jose each have two games remaining, while the Oilers have three.

The victory also extended Anaheim's home winning streak over Calgary to 25 games, the longest streak of its kind in NHL history.

But the Ducks lost defenseman Cam Fowler 6:09 into the third period. Fowler had to be helped off the ice after a knee-on-knee hit in the slot from Calgary's Mark Giordano that sent Fowler sprawling into the boards behind Anaheim's net.

"I just hope he's OK," Giordano said. "There was no intent to hurt him, there. I was just trying to come across and try to stop him from getting to the net. He came through the middle with a lot of speed and I was coming across to make a hit on him. I hope it's nothing too serious. You obviously don't like to see guys get hurt."

After Fowler left the ice, six fights erupted within 10 minutes. Referees Ian Walsh and Brad Watson assessed 106 minutes in penalties in the final 13 minutes, with three game misconducts.

"Obviously, we weren't happy with the hit so we responded the way we did," Bieksa said about the fights before referring to Fowler. "He's one of our best players. It looked like he was in a lot of pain. I'm probably the only guy who didn't get a great look at (Giordano's hit). It didn't look clean. It didn't sound clean."

Anaheim coach Randy Carlyle said Fowler sustained a lower-body injury but offered no specifics. Fowler played in his first All-Star Game in January in Los Angeles.

Mikael Backlund scored for the Flames (44-32-4), who remain one point ahead of the Nashville Predators in the race for the top wild-card berth.

Goalie Brian Elliott made 16 saves after relieving Chad Johnson with 5:19 gone in the game. Johnson left after stopping the only shot he faced, Andrew Cogliano's wrist shot from the left point. That shot appeared to injure Johnson but no report was forthcoming.

Bieksa's third goal of the season broke a 1-1 tie at 13:02 of the second period. Bieksa fired a slap shot from the right circle near the boards that hit Elliott's right leg pad and trickled behind the goalie into the net. Calgary coach Glen Gulutzan challenged the call, which video replay upheld.

Bieksa scored for the first time since Dec. 15 during a 4-3 victory over the Boston Bruins.

Wagner extended Anaheim's advantage to two goals 6:43 into the third period. Wagner scored his fifth of the season by snapping a shot inside the right post after receiving Logan Shaw's pass from the left corner.

The Flames had two chances to move ahead before Backlund scored the game's first goal. T.J. Brodie's long pass from Calgary's zone freed Johnny Gaudreau for a breakaway but Gibson used his glove to deflect Gaudreau's wrist shot before falling on the puck 7:03 into the game.

Nearly six minutes later, Michael Frolik's wrist shot from the right circle during a 3-on-2 attack hit the upper-right corner of the goal frame.

"I thought we played well, especially the first two periods," Giordano said. "We got a lot of looks and we really came out with purpose, especially in the first."

The Flames finally secured a 1-0 lead with 4:41 left in the first period, when Backlund deposited the rebound of Giordano's wrist shot from the blue line inside the right post for his 22nd goal.

"They beat us to a lot of loose pucks in the first period," Carlyle said. "We just seemed slow with the puck early and they had much more jump than we did. We'd have to change the way we were playing."

The Ducks, who managed just one shot on goal in the first 12 1/2 minutes, tied the score 48 seconds into the second period.

Ryan Getzlaf fired a shot off the draw from the left circle in the Flames' zone through Matt Stajan's legs. Elliott blocked the shot with his right leg pad but Eaves converted the rebound into an open net for his career-high 31st goal of the season, eighth in the last nine games and his 10th in 18 contests with Anaheim. Getzlaf recorded his 54th assist.

"We knew that face-off play was coming," Elliott said, "and it still worked."
