Kaepernick remains unsigned despite many teams around the National Football League needing a quarterback, leading many to speculate that there may be a coordinated effort pressuring owners from signing him.
"[NFL owners] have colluded to deprive Mr. Kaepernick of employment rights in retaliation for Mr. Kaepernick's leadership and advocacy for equality and social justice and his bringing awareness to peculiar institutions still undermining racial equality in the United States", the suit claims.
"I think we are reaching people, and there's another handful of people who chose not to hear us". To be honest, I don't know.
"We look forward to another face to face conversation between players and owners", Joe Lockhart, the NFL's executive vice president of communications and public affairs, said in a conference call with reporters Friday.
NFL Commissioner Roger Goodell said that "everyone should stand for the National Anthem" in a letter to NFL teams last week.
Miami Dolphins owner Stephen Ross also said that "it's incumbent on the players" to stand during the anthem.
Kaepernick's decision to kneel during the national anthem remains a divisive topic, and once news of the grievance broke, Urban Meyer's wife, Shelley, took the opportunity to rip Kaepernick on Twitter. "It is an important moment in our game". Honestly, can't really tell you too much.
"We need to move past this controversy, and we want to do that together with our players", he wrote.
The league and union have pledged to work cooperatively on the issue. His protest was misconstrued as disrespect for the country, the flag, and the military, which created an incorrect image of him in the eyes of many.
