"Racism and injustice in our country must end," Kane tweeted Friday. "As a white male in this society, I will never truly understand. But I want to help in this fight for change - and I know I cannot do that in silence."
He announced he was contributing to Chicago charity My Block, My Hood, My City and the Chicago chapter of the national nonprofit All Stars Project, and he encouraged people "to learn more about the many inspirational and impactful organizations serving the black community."
Protests across the country began last week after George Floyd, a 46-year-old black man, was killed in Minneapolis while in police custody.
Kane said he was inspired by My Block, My Hood, My City founder Jahmal Cole, who challenged those looking to denounce racism and spark change to think about "something simple I can do that will have a positive influence on my block."
The 31-year-old winger also shared a video explaining systemic racism that Kane credited for helping him begin to understand the problem.
Former NHL defenseman Mark Fraser, who is black, urged the hockey community to go beyond the internet in order to create true change.
"Social media posts are great, but it can't end there," Fraser wrote Friday. "Don't let an Instagram story be the only thing you did. That's not enough. We need more. George Floyd needs more! Trayvon Martin needs more! Breonna Taylor needs more! Eric Garner needs more! Ahmaud Arbery needs more!"
Dallas Stars forward Tyler Seguin joined a protest in Dallas on Thursday.
