The workout is Kaepernick’s first with an NFL team since his time out of the league began following the 2016 season. That year, he started kneeling during the national anthem before games as a way of protesting police brutality and racial inequality. He later filed a collusion grievance against the NFL, alleging that its owners were conspiring to keep him out of the league. He and former teammate Eric Reid settled their respective grievances.
In the years since, and particularly in recent months, Kaepernick has spoken about his fitness and worked out publicly in an effort to attract interest from NFL teams. He was an honorary captain during Michigan’s spring football game in April, throwing to receivers during halftime. (Michigan coach Jim Harbaugh coached Kaepernick in San Francisco.)
Kaepernick told a Detroit television station afterwards that he was just looking “for an opportunity, for a door to open” with an NFL team.
