George Foreman, Ali’s friend and rival, told the BBC: “We were like one guy—part of me is gone.”

“Muhammad Ali was one of the greatest human beings I have ever met. No doubt he was one of the best people to have lived in this day and age,” he said. “To put him as a boxer is an injustice.”

Ex-heavyweight champ Evander Holyfield told MSNBC: “I’m glad to have known Ali because when I was a kid, at eight years old, I was told I would be like Ali.”
