Frank Gore plans to sign a one-day contract with the San Francisco 49ers before retiring from the NFL.

Five-time Pro Bowler Gore turns 39 in May and did not feature at all last season after going unsigned following one-year spells with the New York Jets, Buffalo Bills and Miami Dolphins.

Prior to that, Gore played for the Indianapolis Colts after spending nine years in San Francisco, where he was selected as a third-round draft pick in 2005 after moving on from the Miami Hurricanes.

Gore, who has the third-most rushing yards in NFL history (16,000), expressed his desire to end his career with the 49ers as he intends to retire before taking up a staff role working for the franchise.

"Probably in a couple months," Gore told 49ers podcast TheSFNiners. "We're still trying to figure out when I'm going to do my one-day contract, to sign, do my retirement.

"I told [49ers chief executive] Jed York that I always wanted to be a Niner. So we're working on that right now, and then we're going to also sit down with me and my agent to talk about me working in the front office.

"I love looking at talent. I love evaluating talent, and I love ball. And they know that I know football players, what it's supposed to take to be a football player."
