Dion Phaneuf was traded to the Los Angeles Kings by the Ottawa Senators for forwards Marian Gaborik and Nick Shore on Tuesday.
Forward Nate Thompson and Phaneuf, a defenseman, will go to Los Angeles.
"I'm going to a team that's won, that has had a lot of success, and I just want to go there and do everything I can to help that team," Phaneuf said. "I'm very, very excited about where I'm going. Right now, it's a lot. To be honest with you, standing here, there are a lot of different emotions, but for me, I'm really excited about where I'm going."
Phaneuf will likely play in a top four that includes Drew Doughty, a Norris Trophy winner; Jake Muzzin and Alec Martinez.
"He should fit into our defense well," Kings general manager Rob Blake said. "We have [three] real good defensemen."

Blake said he was not sure which defenseman Phaneuf would be paired with but said the fact he can play the left or right side was a selling point.
Phaneuf had 16 points (three goals, 13 assists) in 53 games for the Senators this season, including a 6-3 loss at the Pittsburgh Penguins on Tuesday.
Los Angeles plays at Pittsburgh on Thursday and Phaneuf will stay in the city to meet the Kings on Wednesday.
Phaneuf did not play the final 29:15 Tuesday, remaining on the bench in anticipation of the trade.
"I wasn't told right then, but I had an idea," he said. "Then, obviously in between periods, there's the business side of things where the trade call had to go through and stuff."
Thompson was injured and has played four games since Jan. 5.
"We're talking about two players that I really enjoyed having around because they're real character people that brought a lot of positive around us," Senators coach Guy Boucher said. "Two players that I really respect and two guys that I've been far in the playoffs with. … You develop relationships with players. I've always said, for me, it's players, not numbers. That's never going to change."

Gaborik and Shore played to the end of a 7-3 loss to the Carolina Hurricanes. Neither commented afterward.
"The two guys coming in are obviously great players too," Senators forward Matt Duchene said. "I actually know [Shore] pretty well. … Obviously, Marian has a pretty amazing pedigree. So, we'll welcome them in and they're guys that can help us right away."
The Kings, who lost their second straight game, are one point behind the Calgary Flames for third place in the Pacific Division and three points behind the Minnesota Wild for the second wild card into the Stanley Cup Playoffs from the Western Conference.
The Senators are second to last in the Eastern Conference, 16 points out of a playoff position.
"[Phaneuf's] a good friend of mine and a good friend of everybody on this team," Ottawa captain Erik Karlsson said. "Someone that did really well for us. Someone that we would have liked to have kept if the circumstances would've been different, but that's the unfortunate and sad part about the situation that we're in. Things like these are going to happen. We wish him all the best. We know he's going to do real well there."
The 2018 NHL Trade Deadline is Feb. 26 at 3 p.m. ET.
