— 3:57 p.m.: Vancouver added another big-bodied forward for what it hopes will be another Stanley Cup finals run, dealing for 21-year-old Sabres winger Zack Kassian. The Canucks also picked up Marc-Andre Gragnani in exchange for popular rookie Cody Hodgson and Alexander Sulzer. It looks like last year’s Western Conference champions are willing to give up promising youth for a dose of grit. Hodgson, the team’s first-round pick in 2008, told the Vancouver Sun he was “still in shock” after the move. Considered to be in the running for rookie of the year, has 16 goals and 17 assists this season.

The 6-foot-3 Kassian, who was also “stunned” by the deal, has three goals and four assists for the Sabres while Gragnani has a goal and 11 assists this season. In terms of travel, the move couldn’t be more convenient — the two teams face off in Vancouver on Saturday.

The Canucks’ late flurry before the deadline continued as they dealt 22-year-old Swedish prospect Sebastian Erixon to Anaheim for former Capitals draft pick Andrew Gordon. In 37 games for Bruce Boudreau’s Ducks, the 26-year-old Gordon managed two goals and three assists and was a minus-10.

— 3:44 p.m.: The New York Rangers added some more muscle in the form of Chicago defenseman John Scott. Via TSN, they parted with a fifth-round pick for the 6-foot-8 Scott, who won’t provide much in the way of skating, but doesn’t shy away from throwing his 270-pound body around the rink.

Meanwhile, the Predators continued their shopping spree by sending their 2012 first-round pick to Buffalo for center Paul Gaustad and a fourth-round pick. Gaustad has seven goals and 10 assists for the Sabres this season, but its his size (6-foot-4, 229 pounds) that should help Nashville most during their playoff push.

— 3:30 p.m.: The Bruins swung a pair of deals just before the deadline, adding forward Brian Rolston and defenseman Mike Mottau from the Islanders and defenseman Greg Zanon from Minnesota. In return, New York received prospects Yannick Riendeau and Marc Cantin while the Wild get forward Steve Kampfer. The 39-year-old Rolston has four goals and five assists this season, Mottau has two assists in 29 games and Zanon has two goals and four assists. The defending Stanley Cup champions have a three-point edge on Ottawa in the Northeast Division but have lost seven of their last 12.

— 3:20 p.m.: The deadline has come and gone and the Caps roster looks no different. Do you think the team, as it stands, is capable of making the playoffs? Vote here.

— 2:55 p.m.: The Western Conference-leading Vancouver Canucks have acquired center Sami Pahlsson from Columbus in exchange for a pair of 2012 fourth-round draft picks. The 34-year-old Swede has only 11 points this season, but he brings a postseason pedigree after helping the Ducks to the 2007 Stanley Cup. Pahlsson played with the Sedin twins back in Sweden and should give the Canucks’ fourth line a boost.

— 2:05 p.m.: Per TSN, the Winnipeg Jets have sent defenseman Johnny Oduya to Chicago in exchange for a second- and third-round pick. Oduya, 30, has two goals and 11 assists in 63 games and is a minus-9.

Meanwhile, over in Capsland... nothin’ yet.

— 1:55 p.m.: The Lightning made their second move in two hours to add defensive depth, sending 20-year-old prospect Carter Ashton to Toronto for Keith Aulie, as first reported by TSN. The 6-3 Ashton was Tampa’s first overall pick in 2009 (No. 29 overall) and should continue to develop in Toronto’s system. He has 19 goals and 16 assists for the AHL’s Norfolk Admirals this season. The 6-6, 217-pound Aulie, 22, has a pair of assists in 17 games with the Maple Leafs.

— 1:02 p.m.: A pair of Western Conference teams on the outside of the playoff picture swapped defensemen as the Minnesota Wild dealt Nick Schultz to Edmonton for Tom Gilbert. The Wild unload a stay-at-home defender in Schultz in exchange for the more offensive-minded Gilbert, who has three goals and 14 assists in 47 games this season.

— 12:45 p.m.: The Tampa Bay Lightning made a move to bolster their defense, picking up Mike Commodore from the Red Wings in exchange for a seventh-round pick. Commodore has been a near non-factor in Detroit this season, registering only two points in just 17 games, but the 32-year-old has a history with Lightning general manager Steve Yzerman. As Canadian Press reporter Chris Johnston pointed out, Yzerman was the Canadian national team GM in 2007 when Commodore helped the team to a world championship.

— 12:30 p.m.: The trade front is still quiet as can be, but that did not keep Montreal and Winnipeg from upgrading their rosters on deadline day. Via TSN, the Canadiens added forward Brad Staubitz off re-entry waivers from the Wild while the Jets picked up Columbus defenceman Grant Clitsome.

— 11:15 a.m.: Tomas Vokoun came off the ice early at Capitals practice this morning, which sparked some discussion on Twitter over whether the veteran goalie might be traded. But Katie Carrera reports that, at least right now, Vokoun has not been asked to waive his no-trade clause.

— 10:36 a.m.: French-language outlet RDS reports that Montreal winger Andrei Kostitsyn has been traded to Nashville. The move would reunite the 27-year-old with his younger brother Sergei, 24. Kistitsyn has 12 goals and 12 assists in 53 games this season.

Update: The first deal of the day is done. Via TSN, Montreal receives a second-round pick in 2013 and a conditional fifth-round pick in 2013 from the Hall Gill trade.

— 9:35 a.m.: Washington has placed top center Nicklas Backstrom on long-term injured reserve, clearing out some space under the salary cap. The move would give General Manager George McPhee about $7.6 million in room under the cap, but only if Backstrom is out for the rest of the regular season.

As for the rest of the league, no trades to report yet today, and there haven’t been any real blockbusters thus far. The biggest trade leading up to the deadline came Thursday night, when L.A. Kings acquired forward Jeff Carter from the Columbus Blue Jackets in exchange for defenseman Jack Johnson and a first-round draft pick.
