O.J. Simpson retired from professional football ahead of the 1980 season, ending his playing career after eight seasons with the Buffalo Bills and one with the San Francisco 49ers. The decision reflected both persistent injuries and the evolving dynamics of his contract and role on the field. This verified timeline clarifies the official date Simpson last played, the sequence of teams, and the context around his exit from the NFL.
Professional Football Career Overview
Orenthal James Simpson began his NFL career as a running back in 1969 after being drafted by the Buffalo Bills in the first round of the 1969 NFL/AFL Common Draft. Known for his combination of speed, power, and elusiveness, he quickly became one of the league’s most dynamic offensive players. By the late 1970s, injuries and team changes shaped the closing phase of his time in the league.
Buffalo Bills Tenure and Peak Performance
Simpson spent eight seasons (1969–1977) with the Buffalo Bills, establishing himself as one of the premier running backs of his era. He rushed for 6,945 yards and 53 touchdowns with the Bills, earning seven Pro Bowl selections and the NFL Most Valuable Player award in 1973. During this period, he became the first player to rush for over 2,000 yards in a single season in 1973, a record that stood for decades.
Transition to the San Francisco 49ers
Prior to the 1978 season, Simpson was traded to the San Francisco 49ers. The move was part of a larger restructuring by Buffalo and offered San Francisco a chance to bolster a backfield that had struggled with consistency. Simpson played one full season with the 49ers in 1978, carrying the ball 259 times for 958 yards and four touchdowns, then started the 1979 season on the roster before injuries curtailed his role.
Formal Retirement Announcement and Timeline
Simpson officially announced his retirement in late March 1980, concluding a nine-season professional career. NFL records show his final game as a player occurred during the 1979 season with San Francisco, with his last regular season appearance coming in December 1979. The timing of his retirement was driven by chronic knee issues and a desire to pursue broadcasting and business opportunities.

Context Around Retirement Decision
