Zdeno Chara of the Boston Bruins, Erik Karlsson of the Ottawa Senators and Shea Weber of the Nashville Predators were named finalists for the Norris Trophy, which is given to the league's top defenseman.
Chara, whose season ended Wednesday night with the Bruins' 2-1 overtime loss to the Washington Capitals in the Eastern Conference first-round series, is a five-time Norris finalist, winning the award in 2009.
He had a career-high 52 points this season (12 goals, 40 assists), fourth-best among all defensemen, and tied for third among all players with a plus-33. Chara, 35, played his 1,000th game in March and was a captain at the 2012 All-Star Game.
Karlsson, 21, broke out this season with 78 points -- 25 more than any other defenseman, and tying him for 10th-most among all players.
He had 59 assists, best among the league's defenders, and tied with Weber with 19 goals.
Weber, 26, had a career-best 49 points, tying him for sixth in the league overall, and scored 10 goals on the league's top power-play unit. His average ice time of 26 minutes, 9 seconds was fifth-most in the league.
Weber was a Norris finalist last season, finishing second in voting to Detroit's Nicklas Lidstrom.
The winner will be announced at the NHL awards ceremony June 20 in Las Vegas.
