According to Adam Schefter of ESPN, the 49ers and running back Frank Gore have agreed to a three-year, $21 million dollar extension with $13.5 guaranteed.

Gore didn’t play in last Saturday’s 30-7 loss to the Houston Texans, and Harbaugh wouldn’t say whether he would play in Thursday night’s exhibition finale at San Diego. It’s nothing new for him to sit, as Gore has rarely played during the preseason in the past.

Gore needs 931 yards to become the franchise’s all-time leading rusher. While that is a goal, he also wants to have a big year to help turn the 49ers around after eight straight seasons without a playoff berth or winning record.
