Santa Clara, CA (SportsNetwork.com) - The San Francisco 49ers signed guard/center Daniel Kilgore to a three-year contract extension through the 2017 season on Thursday.

"We are pleased to extend the contract of a talented, young player like Dan," said general manager Trent Baalke. "This move is another example of our philosophy to extend the contracts of our own young players."

Originally selected by the 49ers in the fifth round (163rd overall) of the 2011 NFL Draft, Kilgore has appeared in 33 regular-season games during his three-year career.

He appeared in all 16 regular-season games and all three postseason contests in 2013.
