" Frank Gore knows it would be a novelty if he played his entire career with the 49ers. He relishes that prospect.

"You rarely see running backs get to finish their career with the team that drafted them," Gore said. "Obviously, I'm one of them."

He is now slated to serve a decade in a 49ers jersey after signing a three-year, $21 million contract extension through the 2014 season Wednesday. He was entering the final year of a deal paying him $4.9 million this season."
