Muhammad Ali v. Jimmy Ellis, July 26, 1971.
This was Ail's first fight after losing to Joe Frazier in March 8 of that same year. Growing up together in Louisville, KY, Ali and Ellis were occasional sparring partners. They were also friends. Ali was faster and stronger, but dragged the match out 12 rounds, until he called for the fight to end so his friend wouldn't be hurt anymore.
