Warriors forward Juan Toscano-Anderson, an Oakland native, led the march. Toscano-Anderson signed a contract with the Warriors in February after opening the season with their G League affiliate.
Curry's wife, Ayesha, also attended the rally. They joined the crowd in chanting the name of George Floyd, a black man who died May 25 after former Minneapolis officer Derek Chauvin, who is white, knelt on his neck for nearly nine minutes.
Golden State guard Damion Lee and center Kevon Looney were also in attendance, according to ESPN's Nick Friedell. The peaceful march took participants around Lake Merritt, where the Warriors have celebrated recent NBA championships, Friedell notes.
Toscano-Anderson addressed the crowd to close out the event.
The Warriors moved to Oakland full time in 1971 and were based there through the 2018-19 season. They returned to San Francisco ahead of the current campaign.
