Muhammad Ali vs. Antonio Inoki took place in Japan in 1976. The classic match-up between professional boxer and professional wrestler turned sour as each fighter refused to engage in the other's style, and after a 15-round stalemate it was declared a draw. Muhammad Ali sustained a substantial amount of damage to his legs, as Antonio Inoki slide-kicked him continuously for the duration of the bout, causing him to be hospitalized for the next three days. The fight played an important role in the history of mixed martial arts. In Japan, the match inspired Inoki's students Masakatsu Funaki and Minoru Suzuki to found Pancrase in 1993, which in turn inspired the foundation of Pride Fighting Championships in 1997. Pride was acquired by its rival Ultimate Fighting Championship in 2007.
