Panthers trade Radek Dvorak

The Florida Panthers have traded forward Radek Dvorak and a fifth-round pick in this year's draft to the Atlanta Thrashers in exchange for forwards Niclas Bergfors and Patrick Rissmiller.

Dvorak, 33, and Rissmiller, 32, both are scheduled to become unrestricted free agents July 1.

Dvorak is joining his fifth team. He has seven goals and 14 assists this season.

Rissmiller has played mostly in the AHL the past two seasons.

Bergfors, 23, signed a one-year, $900,000 deal with the Thrashers in September 2010. He was part of the February 2010 trade that sent longtime Thrashers star Ilya Kovalchuk to the New Jersey Devils.

Bergfors, a restricted free agent at the end of the season, has 11 goals and 18 assists this season.

In a second trade, the Panthers sent defenseman Dennis Wideman to the Washington Capitals for prospect Jake Hauswirth and a third-round 2011 pick.

Wideman, 27, has one more year on his contract, worth $3.9 million. He had 33 points (nine goals, 24 assists) and 33 penalty minutes while playing in 61 games for the Panthers.

The move gives the Capitals more scoring punch on the blue
line and adds needed depth as they deal with injuries to
Mike Green and Tom Poti.

Green was injured earlier this month when he took a puck to the head in a game against the Penguins. Poti has been battling a groin injury.

Hauswirth, 23, has 10 goals and four assists in 37 games with the South Carolina Stingrays of the ECHL this season.

The Panthers continued their downsizing by moving defenseman Bryan Allen to the Carolina Hurricanes in exchange for veteran winger Sergei Samsonov.

Allen, who has one more year left on a contract that will pay him $2.9 million, will add depth to the Hurricanes' defense as they try to hold onto a playoff position in the Eastern Conference.

Samsonov, who has 10 goals this season, will be an unrestricted free agent this summer.

Later in the afternoon, the Panthers sent Chris Higgins to the Vancouver Canucks defenseman Evan Oberg to Florida and a 3rd round pick in 2013.

Coyotes get Klesla from Blue Jackets

The Coyotes acquired defenseman Rostislav Klesla and forward Dane Byers from the Columbus Blue Jackets in exchange for forward Scottie Upshall and defenseman Sami Lepisto.

Klesla, 28, a former first-round pick by the Blue Jackets and their last original player, has three goals and seven assists in 45 games this season. Klesla -- hampered by injuries the past two seasons -- has three years remaining on a contract that pays him
almost $3 million a year, through the 2013-14 season.

Byers, 25, has spent this season in the minors with the AHL Hartford and Springfield teams.

"When Ed Jovanovski [fractured orbital bone] got injured, we felt very vulnerable on our
blue line, especially in the defensive-matchup, penalty-killing
role," Coyotes general manager Don Maloney said. "We searched for what we
hoped was a top-four defenseman who could match up against good
players. This deal really came up today and it was a case where we
had to give to get."

The Blue Jackets and Coyotes both are fighting for spots in the
crowded Western Conference playoff race.

Upshall, 27, had 16 goals and 11 assists this season and 80
goals and 85 assists in 340 career games with Nashville,
Philadelphia and Phoenix.

Lepisto, 26, has four goals and seven assists this year and five
goals and six assists in 131 career games.

Upshall, making $2.25 million this year, is an unrestricted free
agent after the season. Lepisto, a restricted free agent after the
season, is making $800,000.

Just before the deadline, the Blue Jackets also dealt left wing
Tom Sestito to the Philadelphia Flyers for former Columbus center
Greg Moore and center prospect Michael Chaput.

Ducks get Winchester, Perrault

The Anaheim Ducks acquired forward Brad Winchester from the St. Louis Blues in exchange for a third-round pick.

Later, the Ducks announced it had acquired center Joel Perrault and a third-round selection in the 2012 draft from the Vancouver Canucks for centers Maxim Lapierre and MacGregor Sharp.

Rangers trade for Mitchell

The New York Rangers acquired center John Mitchell from the Toronto Maple Leafs for a seventh-round draft pick.

Mitchell, 26, has spent most of his time this season with the AHL Toronto Marlies. The Rangers assigned him to AHL Connecticut.

Bruins, Wild engage in minor trade

The Minnesota Wild have traded goaltender
Anton Khudobin to the Boston Bruins for two 23-year-old prospects.

The Wild
get defenseman Jeff Penner and right wing Mikko Lehtonen.

Khudobin went 4-1 with a 1.40 GAA in six
starts for the Wild as an injury fill-in the past two years. He has a .911 save percentage in 34 games for Houston in the AHL
this season.

Penner has five goals and 14 assists in 57 games for AHL Providence this season. Lehtonen is second in the Swedish Elite League in scoring this
season with 29 goals and 27 assists in 52 games. The native of
Finland played the previous two years with Providence
