The 49ers this week pledged $1 million to a pair of Bay Area groups for "improving racial and economic inequality," team CEO Jed York said.
The groups include the Silicon Valley Community Foundation and The S.F. Foundation.
Colin Kaepernick after his final preseason game against the Packers vowed to donate his first $1 million of earnings this season to various organizations.
On Wednesday morning, the quarterback let it be known that he will be giving additional money.
"I want to thank everyone who has shown me love and support, it truly means a lot!" Kaepernick wrote on Instagram. "I wasn't expecting my jersey sales to jump to number one because of this, but it shows the people's belief that we can achieve justice and equality for ALL!
"The only way I can repay you for the support is to return the favor by donating all the proceeds I receive from my jersey sales back into the communities! I believe in the people, and WE can be the change!"
Over the 49ers' four exhibition games, Kaepernick did not stand for the national anthem.
In the first three games, he remained seated on a bench. In the finale, he elected to take a knee on the sideline.
ESPN's Jim Trotter first reported the charitable donation by the 49ers.
York issued the following statement on Thursday regarding the $1 million pledge:
"Today, I am committing that the 49ers Foundation will contribute $1 Million to the cause of improving racial and economic inequality and fostering communication and collaboration between law enforcement and the communities they serve here in the Bay Area.
We are partnering with the Silicon Valley Community Foundation and the San Francisco Foundation in this effort. We have chosen to work with these two organizations because they have proven track records of affecting change in the face of challenging problems and have the collective reach to make the greatest impact. Silicon Valley Community Foundation is the largest community foundation in the world, managing $7.3 billion in assets and more than 1,800 philanthropic funds globally. The San Francisco Foundation has served the people of the Bay Area since 1948, almost as long as the 49ers franchise. We are excited to work with these two renowned foundations over the coming months to develop a giving plan to help our community find unifying solutions to these pressing issues.”
