The Toronto Maple Leafs dealt forward John Mitchell to the New York Rangers on Monday for a seventh-round pick in 2012.

The 26-year-old forward had been playing for Toronto's AHL team.

Mitchell spent his entire career with the Maple Leafs organization after being a fifth-round draft pick in 2003.

In 159 career NHL games, he has 20 goals and 55 points.

It was the only move made by the Leafs on deadline day.

Meanwhile, the Florida Panthers' fire sale rages on.

The Panthers sent defenceman Dennis Wideman to the Washington Capitals and forward Radek Dvorak to the Atlanta Thrashers in a pair of deals ahead of the NHL trade deadline on Monday.

Florida general manager Dale Tallon had dealt away veterans Bryan McCabe, Cory Stillman and Michael Frolik earlier this month.

Wideman went to the Capitals for forward prospect Jake Hauswirth and a third-round draft pick. He sent Dvorak and a fifth rounder to Atlanta for 23-year-old Niclas Bergfors and 32-year-old journeyman Patrick Rissmiller.

The deals have left the rebuilding Panthers with 10 picks in the 2011 draft, including seven in the first three rounds.

"We continue to set ourselves up to have another franchise-building draft this summer," Tallon said in a statement. "Our confidence in our current corps of defencemen -- both in the NHL and throughout our organization -- allowed us to make this (Wideman) trade and acquire another high pick in the 2011 draft."

Another deal saw the Columbus trade away defenceman Rostislav Klesla, the last original Blue Jacket, to the Phoenix Coyotes for physical forward Scottie Upshall and defenceman Sami Lepisto. Klesla was the Jackets' first draft pick in their first season in 2000.

The 27-year-old Upshall has 16 goals this season while 26-year-old Lepisto has four goals and seven assists.

The Los Angeles Kings signed forward Justin Williams to a four-year contract extension worth US$14.6 million.
