San Jose, CA -- (Sports Network) - The San Jose Sharks signed defenseman Marc- Edouard Vlasic to a four-year contract extension, the team announced on Wednesday. Per club policy, financial terms of the deal were not disclosed.

Vlasic, 21, played in all 82 games for the Sharks last season, notching two goals and 12 assists in his second year with the club. A second-round choice (35th overall) in the 2005 NHL Draft, Vlasic was named to the All-Rookie team in 2006-07 after scoring three goals with 23 assists in 81 games.

"Marc-Edouard is one of the top young defensemen in the game and we are excited to have him in the fold for the next several years," said Sharks general manager Doug Wilson. "He has a tremendous future with this franchise and we look forward to watching his continued development."

The 6-foot-1, 200-pound Montreal native also ranked third on the team in blocked shots (85) and average ice time (21:36) last season.
