It started 14 months ago, when then-49ers quarterback Colin Kaepernick became the first NFL player to kneel during the national anthem to protest social injustice and police brutality. Last week, following controversial remarks by President Trump referring to any player who would kneel as a "son of a b----," all 32 teams staged pregame demonstrations as a show of unity.

Kaepernick may still be a free agent, but on Sunday his former team took part in a display of unity that included at least 30 players kneeling during the anthem. Other teammates stood behind them and everyone on the 49ers' sideline appeared to have their hand over their hearts.

The 49ers also released this statement:

"At its purest level, football is a unifier of people from all walks of life, different socio-economic backgrounds, every corner of this country and around the world. As players, coaches, ownership and staff, we are privileged to work in an environment that is a tremendous example of how people can come together for a common goal. We not only put our differences aside, but we also use them to achieve that common goal by challenging each other to be better -- both in our professional and personal lives.

"For more than a year, members of our team have protested the oppression and social injustices still present in our society. While some may not have taken a knee or raised a fist, we have all shared the desire to influence positive change. Today, our team chose to publicly display our unity in a new way and, in turn, urge others do the same. Our demonstration is simply a representation of how we hope our country can also come together by putting differences aside and solving its problems.

"As the majority of us have done throughout our careers, we use our platform as members of a NFL team, and our right to freedom of expression, to speak up for those whose voice is not heard. It is important that we continue to emphasize that despite our different backgrounds and beliefs, we still love each other and are truly a brotherhood. Our gesture today was an intentional effort to demonstrate that. Make no mistake, we love this great country and have tremendous respect for our military and veterans who have sacrificed so much for our right to express ourselves freely. We passionately want what is best for this country and all its citizens.

"On behalf of the San Francisco 49ers organization, we urge our fellow citizens to embrace your differences, find strength in them, and come together for the good of all."

Hours earlier, Ravens fans booed their team for kneeling in prayer before the anthem. For more on how every NFL team chose to protest, read this.
