Ed. Note: We're live blogging every hour of the NHL trade deadline until its completion at 3 p.m. EST. Older time-stamped entries are found at the end of the post.
10:47 a.m. ET: We have our first deal! Dale Tallon gets his day started by dealing Radek Dvorak and a fifth-round pick to the Atlanta Thrashers for Niclas Bergfors and Patrick Rissmiller.
Dvorak is scheduled to become unrestricted this summer and has seven goals and 21 points this season. Bergfors will be restricted on July 1 and has scored 11 times and tallied 29 points through 52 games with Atlanta.
Bergfors, you'll remember, recorded 21 goals in his rookie campaign last year and was red-hot after being part of the Ilya Kovachuk deal.
One Milbury floating head here. Both teams helped here if Bergfors and Dvorak are re-signed in the summer. Given Bergfors' history immediately after being traded, he might just go on a nice scoring tear for the Panthers. Florida gets younger, while Thrashers GM Rick Dudley adds some veteran depth up front as the team makes a playoff push in the Eastern Conference.
10:38 a.m. ET: Two weeks after being dealt to the Atlanta Thrashers from the Boston Bruins, defenseman Mark Stuart has signed a new three-year deal worth $5.1 million.
10:25 a.m. ET: Because he hasn't been re-signed by the New York Islanders, center Zenon Konopka has garnered some interest as 3 p.m. ET approaches and while initial reports this morning had Vancouver pegged as a possible destination, Chris Botta of Islanders Point Blank/Fanhouse shot that idea down:
A Canucks source to Point Blank a minute ago: "I've heard the rumors, but Zenon Konopka is not high on our wish list. He's not even in the middle of our list."
The "Brad Richards Watch" continues as the New York Post's Larry Brooks reported this morning that Dallas Stars GM Joe Nieuwendyk lowered his demands from a week ago from the New York Rangers. Brooks reports that the asking price for Richards is now Artem Anisimov, a No. 1 pick and a top prospect. On Thursday, Brooks reported that Nieuwendyk had asked for Derek Stepan, Brandon Dubinsky and Marc Staal.
10:10 a.m. ET: Florida Panthers center Stephen Weiss is one of the names that could be on the move today and according to Sportsnet's Nick Kypreos, he'll only waive his no-trade clause to move to the Toronto Maple Leafs. Ken Campbell of The Hockey News says it's not true that Weiss would only waive his NTC to go to the Leafs. Deadline Day fun already!
Decisions ahead for Panthers GM Dale Tallon as he also has David Booth, Tomas Vokoun and Marty Reasoner as potential trade targets from other teams.
Meanwhile, Leafs forward Clark MacArthur looks like he'll be staying in the blue and white for at least the rest of this season, despite drawing plenty of interest on the trade market.
Meanwhile, MacArthur's agent, Don Meehan of Newport Sports. told The Star from New York late Sunday that he does not believe the Leafs intend to trade his client on Monday unless they get a boffo offer out of the blue.
"My impression is they want to make a deal with Clarke," said Meehan. "They'll watch him for the balance of the year, see how he does, see how the team does, and then reflect on that. It's not something they have to do right now."
And a signing as we kick off Hour 3. TSN's Bob McKenzie reports that Justin Williams has inked a four-year extension worth $14.6 millon deal with the Los Angeles Kings. Williams has 20 goals and 49 points in 62 games with the Kings this season after being acquired from Carolina at the 2009 trade deadline.
