The short answer
Colin Kaepernick last played in the NFL during the 2016 season with the San Francisco 49ers. He became an unrestricted free agent after the season and was not signed by another team, which he attributes in part to league actions tied to his national anthem protests. He did not officially retire, has remained outside the league since 2017, and filed a grievance in 2017 alleging collusion under the league’s collective bargaining agreement. This explainer separates verified timelines and contractual facts from ongoing disputes and activism context.
2016: final season on an active roster
In 2016, Kaepernick started 15 games for the 49ers, compiling a 69.1 passer rating, 1,894 yards, 10 touchdowns, and 10 interceptions. The 49ers finished 2–14 and head coach Chip Kelly elected to part ways with Kaepernick in favor of backup Blaine Gabbert. His contract was fully guaranteed, and he was released on March 3, 2017. The 2016 season was the last in which he appeared on an active roster and threw a pass in an NFL game.
On field contributions in 2016
That season included several notable performances, such as a four touchdown, 284 yard game against the Packers in Week 2. The 49ers ranked 24th in yards per attempt and 27th in passer rating when he started, reflecting both his limitations and the constraints of the team around him. Still, his 69.1 season passer rating remains his career high.
Post 2016: free agency and the grievance
After clearing waivers following his release, Kaepernick declared himself a free agent but went unsigned. He maintained he was effectively blacklisted for kneeling during the national anthem to protest racial injustice. In August 2017, he and his legal team filed a grievance against the NFL under the league’s collective bargaining agreement, alleging that owners and team officials had colluded to keep him out of the league. The grievance proceeded through the arbitration process, which ultimately sided with the league in 2018.

Contract and financial context
Kaepernick’s contract with the 49ers included full guarantees, which he received upon his release, ensuring no financial penalty for the team at that release point. In subsequent years, he opted out of contracts with incentive-heavy structures, emphasizing control over his work and public positions. While his absence from rosters has persisted, the financial resolution of his release clarified that team decisions, not penalties, governed his exit from active play.
Benchmarks and context
Placing Kaepernick’s exit in context among quarterback departures can clarify how his path differed:
- Departures following expansion or roster cuts typically involve waivers and quick re-signings; Kaepernick remained on unconditional release status.
- Many veteran quarterbacks transition to other leagues or roles; Kaepernick did not sign with another professional football league.
- Grievances over collusion are rare; his case became one of the highest profile NFL labor disputes involving quarterback availability.
National anthem protests and public discourse
Kaepernick first knelt during the national anthem in 2016 to spotlight racial inequity and police violence. The protests drew polarized reactions from fans, owners, and media, and intensified narratives linking his on field performance to off field messaging. The intersection of activism and roster decisions has remained central to public discussion about why he has not returned to the league, even as the factual timeline of his last season and release is well established.
Path not taken: other leagues and roles
Since leaving the NFL, Kaepernick has not returned to professional football in any official capacity, nor has he joined alternative football leagues. He has engaged in philanthropy, media projects, and public advocacy, but roster moves or league negotiations have not progressed. This distinguishes his situation from athletes who transitioned to other leagues or advisory roles after leaving their original sport.
