Free-agent quarterback Colin Kaepernick filed a grievance against the NFL, accusing the 32 owners of collusion, his legal team announced on Sunday.
Kaepernick has remained unemployed through the first six weeks of the NFL season, even when injuries to other quarterbacks created job openings. He retained attorney Mark Geragos to represent him.
"We can confirm that this morning we filed a grievance under the CBA on behalf of Colin Kaepernick," Geragos said in a statement, in reference to the collective bargaining agreement.
"This was done only after pursuing every possible avenue with all NFL teams and their executives.
"If the NFL (as well as all professional sports leagues) is to remain a meritocracy, then principled and peaceful political protests -- which the owners themselves made great theater imitating weeks ago — should not be punished and athletes should not be denied employment based on partisan political provocation by the Executive Branch of our government. Such a precedent threatens all patriotic Americans and harkens back to our darkest days as a nation. Protecting all athletes from such collusive conduct is what compelled Mr. Kaepernick to file his grievance.
"Colin Kaepernick's goal has always been, and remains, to simply be treated fairly by the league he performed at the highest level for and to return to the football playing field."
The 29-year-old Kaepernick said his agent reached out to all 32 teams to make sure they were aware of his interest in playing this season. He opted out of his contract with the San Francisco 49ers in the offseason.
Kaepernick has been a controversial figure since he first sat and then knelt during the national anthem before games with the 49ers in the 2016 season. The move was the beginning of what turned into league-wide protests earlier this season after U.S. President Donald Trump made critical comments of players who don't stand for the national anthem.
