Immediately after the anthem, the 49ers issued a statement said to be from the players, coaches, ownership and staff.
"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," the statement said. "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.
