49ers sign center Daniel Kilgore to 3-year extension

Less than a week after signing their franchise quarterback, the 49ers secured the services of one of the players who will be charged with protecting their $137.5 million investment. On Wednesday, six days after Jimmy Garoppolo signed a five-year deal, the 49ers signed center Daniel Kilgore to a three-year contract extension. Kilgore, 30, who was a pending free agent, is a 2011 fifth-round pick who is the team's second-longest tenured member behind left tackle Joe Staley. Last year, Kilgore started a career-high 16 games and won the team's Bobb McKittrick Award, an honor voted on by his fellow offensive linemen, which recognizes qualities such as courage and intensity.
