The Sharks have agreed to a one-year contract extension with defenseman Jason Demers, the club announced on Thursday. The deal is worth $1.5 million, according to a source.

Demers was due to become a restricted free agent.

"Jason is a highly competitive, puck-moving defenseman that creates offense from the back end," GM Doug Wilson said in a statement. "We're looking forward to seeing him come back healthy and continuing his growth with us."

Demers had three points in 22 games with the Sharks in 2013 (1g, 2a), but played in just one playoff game due to a high left ankle sprain. He missed the first seven games of the shortened season due to a wrist injury suffered overseas during the NHL lockout, and four games from March 30-April 5 with a possible concussion after a hit to the head from Detroit’s Cory Emmerton.

“He’s a player we really like, he just needs to be healthy,” Wilson said. “He’ll have a great summer of training and come back and play the way he’s capable of, because he brings an element that we certainly like in our game.”

Demers played 30 games in Finland for Karpat during the lockout, scoring five goals and adding 16 assists for 21 points. He was injured in the Spengler Cup, just days before the NHL announced the end of the brutal work stoppage.

“Last year I had a lot of momentum coming in, especially overseas. It’s bad luck, or whatever you want to call it,” Demers said. “It just kind of spiraled from there. I still have some positive things to take from last year, and I’m going to apply those this summer and keep progressing and get better, and get to the player that I know I can be, and they know I can be.”

Demers had his best season as a professional in 2010-11, with 24 points (2g, 22a). Since then he’s had trouble staying healthy, but even when at 100 percent, Demers hasn’t been able to maintain a regular place in the Sharks’ lineup. This past season, he played just nine times in a 20-game stretch from Feb. 2 to March 16.
