Five-time Pro Bowl running back Frank Gore intends to sign a one-day contract with the San Francisco 49ers and announce his retirement from football this offseason, he told TheSFNiners.

"Probably in a couple months," Gore said about his retirement. "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 owner) 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 ... to talk about me working in the front office."

Gore, who's rushed for the third-most yards in NFL history, didn't play last year after appearing in 15 games with the New York Jets in 2020.

The 38-year-old spent the majority of his career with the 49ers, who drafted him in the third round in 2005. He became San Francisco's all-time rushing leader after racking up 11,073 yards and also accrued 64 touchdowns through 10 seasons with the team.

Gore joined the Indianapolis Colts in 2015 and played three seasons in the AFC South. He rushed for at least 900 yards each year, topping the 1,000-yard mark for the ninth time in 2016.

The Miami product also had one-season stops with the Miami Dolphins (2018) and Buffalo Bills (2019).

Gore's 16,000 career regular-season rushing yards rank third all time behind only Emmitt Smith (18,355) and Walter Payton (16,726). Adrian Peterson is the next active player on the list at No. 5 with 14,918.

A member of the NFL's 2010s All-Decade Team, Gore also ranks third in career rushing attempts (3,735) and 19th in rushing touchdowns (81). He will retire with the most games played by a running back (241).

In college, Gore helped Miami win a national title in 2001.
