A handful of legends have retired over recent years as the NFL's greats leave the league behind for life outside of football. After 16 seasons, future Hall of Fame running back Frank Gore finally hung up the cleats. Before so, the San Francisco 49ers signed him to a one-day contract so he can retire with the team he began his career with.

During his final day with the 49ers, Gore sent an emotional message to San Francisco fans. It was awesome for the franchise to sign him to a one-day deal, as Frank Gore played an integral part for the team during his prime. Now, the legendary running back moves on to bigger and better things away from football.

During his career, the former 49ers running back accumulated 16,000 rushing yards, 81 touchdowns, and a 4.3 yards per attempt average. He was known as a downhill runner who punished defenders frequently. Many didn't see Frank Gore having the career he has had, as he entered the NFL with two ACL injuries during his tenure at the University of Miami.

Regardless, Gore played 16 seasons in the league. 14 of those seasons he played as the top option out of the backfield, which is just absolutely insane. Especially considering the career length for running backs is typically much shorter than other positions in football. Even so, Gore proved to be reliable throughout his entire career and showed off his best skills during his time with the 49ers.

Congratulations to Frank Gore for a historic career in the NFL!
