Ducks, looking for toughness, acquire wing Tim Jackman from Calgary

After watching the Ducks be outscored 8-2 after the second period during their current five-game winless streak, General Manager Bob Murray made a trade Thursday with increased grit in mind.

The Ducks sent a sixth-round pick in next year’s NHL entry draft to the Calgary Flames in exchange for right wing Tim Jackman, a tough, 225-pound veteran who already has 41 penalty minutes in 10 games this season.

The durable Jackman, 32, played in all 82 games for the Flames in 2010-11, scoring a career-best 13 goals with 23 assists. He has played in more than 400 NHL games as a member of Columbus, Phoenix, the Kings and New York Islanders. Jackman earns $612,500 this season.

Koivu working hard

Saku Koivu was drenched in sweat after skating hard and shooting pucks past goalie teammate Viktor Fasth Thursday in an optional practice.

The Ducks’ veteran center might find it tempting to declare himself ready to return to a team that could use his influence, considering the winless streak.

But after missing 12 games since he suffered his first NHL concussion on Oct. 27 in Columbus, Koivu is still experiencing occasional dizziness and doesn’t know when doctors will let him return.

“You’ve got to be honest with them,” Koivu, 38, said. “We’ve got 60 games to go and you’re not going to rush it with these type of things. You want to be back, no doubt. But I’m not doing anything until I’m symptom-free.

“It’s day by day, you wait until all the symptoms are gone and then they clear you.”

Koivu was examined Wednesday and was not given clearance to engage in physical contact.

Not time to snap

If ever the time seemed right for a Ducks leader to bark at his teammates, it would have been after Wednesday’s 4-3 loss to the New Jersey Devils. The Ducks played another tentative third period and lost by hitting a puck off a teammate and into their own goal in overtime.

Instead, Ryan Getzlaf let others interpret the collapse and find their own motivation.

“Just my feel for the room,” Getzlaf said as the first-place Ducks (15-6-3) prepared for Friday night’s home game against the Tampa Bay Lightning (14-7 before facing San Jose on Thursday night). “When you’re going through something like that, it’s more about sticking together to get things back on track.”

Ducks forward Kyle Palmieri said some veterans shared their perspective about how “to get out of” the losing streak and focus on getting payback by beating the Lightning. The Ducks were trounced at Tampa Bay, 5-1, on Nov. 14. Getzlaf was sidelined for that game by an upper-body injury.

“Everyone now has to put their best foot forward like they did to us,” Palmieri said.
