Sekera, 27, leads Carolina defensemen with 44 points (11 goals), third on the team, although he hasn't played since April 1. He leads the Hurricanes in blocked shots (127) and average ice time (23:40).
The Hurricanes acquired Sekera in a trade with the Buffalo Sabres at the 2013 NHL Draft.
They said, 'You're going to love the city. It's smaller than Philadelphia, but you're going to love it. You're going to love the fans. Just watching the playoffs last year, the fans seemed louder there than they did anywhere. I'm really excited about that.
