In a statement released on October 15, Colin Kaepernick’s lawyers wrote: “We can confirm that this morning we filed a grievance under the CBA on behalf of Colin Kaepernick.
“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 protest – which the owners themselves made great theatre imitating weeks ago – should not be punished and athletes should not be denied employment.
“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.”

“It was our goal to be unified as a team and to be respectful of everyone’s opinions, and the remembrance of 9/11.
“It’s our job as professional athletes to make a positive impact on our communities and to be proactive when change is needed,” a statement from the Chiefs players after the game said.
Miami Dolphins player Jelani Jenkins said: “I chose to get involved to see if I could create change, raise awareness.
“I want to make it clear that there is no disrespect to the military or to police officers – I’m not about that.
“I would like to keep moving forward in the right direction with everybody: equal rights, equal opportunity. From my position, it doesn’t seem that it’s happening. That’s why I took a stand.”
Seattle Seahawks players and staff had been in talks before their game to discuss how best to show support, and wide receiver Doug Baldwin said they wanted to meet with the mayor of Seattle and local law enforcement.
“We know that there has to be change and progress, but you got to apply direction to change,” he said.
