Santa Clara, CA -- (Sports Network) - The San Francisco 49ers have signed Joe Staley to a six-year contract extension, keeping the offensive tackle in the Bay Area through the 2017 season.

The 6-foot-5, 315-pound Staley has not missed an offensive snap with the club since being selected 28th overall in the 2007 draft.

"Joe Staley is the type of player we want to continue to add to this football team," said 49ers general manager Scot McCloughan. "He's a tough, versatile, no-nonsense type of guy who wants to do whatever it takes to help his team win football games. Joe is a consummate team player and has been completely unselfish in the way he has approached his role on this team."

Staley became the first Central Michigan player selected with a first-round pick. He started 39 of the 46 games he played in college and helped his team produce 1,000-yard rushers in three of his four seasons.
