Muhammad Ali tribute

LeBron James, Stephen Curry honour boxing legend during NBA Finals series

Ali, who died Saturday (AEST) at age 74, was recalled for his sacrifices and struggles for social justice, as well as his boxing career, by the two giants of the NBA.

The late boxer lost three prime years of his career for his stand against fighting in the Vietnam War before the US Supreme Court vindicated him in 1971.

"When an icon like Muhammad Ali passes away, it's just very emotional," James said.

"It's also gratifying to know that guy, one man, will sacrifice so much of his life knowing it will better the next generation of men and women after him."
