According to Sports Illustrated, the former San Francisco 49ers player filed the grievance against NFL owners on Sunday with claims they are participating in collusion to keep him out of the league.
After opting out of his contract last season, the 29-year-old has since been a free agent. In 2016, he was one of the NFL's biggest stories after deciding to kneel during the national anthem to protest and raise awareness for racial inequality in the U.S.
Like with everything related to Kaepernick that has come to light in recent weeks, particularly with the rhetoric Donald Trump has shared that those kneeling should be "fired," social media opinions varied widely on him taking action against the very organization he grew up loving.
Some don't believe he can win the case...
Colin Kaepernick has a 0% chance of winning a collusion lawsuit. Frankly, this entire story has become pathetic.— Clay Travis (@ClayTravis) October 15, 2017
Unless there’s a smoking gun (email, text, someone on the record etc.) Colin Kaepernick won’t win this. Almost impossible to PROVE https://t.co/UAVgYV47it— Eric Rosenthal (@ericsports) October 15, 2017
Guess @Kaepernick7 wants to feel what it’s like to lose again— #BackTheBlue (@ScottR1327) October 16, 2017
Some think it's just a publicity stunt...
Be mad at me for this if you want but Colin Kaepernick filing grievance against NFL owners for collusion is a textbook publicity stunt— Matt Bailey (@MattxthexBailey) October 15, 2017
While others think he should sue the president...
@Colin Kaepernick in my opinion,you should sue the fake potus of the USA for trying to deny your Constitutional Right to peacefully protest— Chris Curry (@nanna1932) October 15, 2017
With Aaron Rodgers now injured, some believe it's kismet to make a comeback.
With reports surfacing that he could miss the remainder of the season, fans are hoping Kaepernick can come back.
If Colin Kaepernick is the best QB option for #Packers, sign him.
If not, don't.
But let decision solely be about football. Not politics.— Jay Sorgi (@jsorgi) October 15, 2017
Sad news about Aaron Rodgers. I know a quarterback looking for a job that was born in Milwaukee... Colin Kaepernick— Josiah Johnson (@KingJosiah54) October 15, 2017
If Rodgers is injured for an extended period of time, the Packers should sign Colin Kaepernick. Maybe the one FA QB that can keep us in it— Jed Butter (@Jbursik21) October 15, 2017
Others still really believe in the Kap, no matter what...
Would love seeing Colin Kaepernick hired by the Green Bay Packers, just to witness the patriotic response of their fans if he took a knee.— Joelon Wilson (@futureicon) October 15, 2017
Colin Kaepernick to @packers make it happen. Would love for my favorite player to make a comeback.— Joseph Nau (@JoeyNau631) October 15, 2017
I would love to see Colin Kaepernick become a Green Bay @Packer!— Ellen (@ellemc20) October 15, 2017
