Did Muhammad Ali fight a sumo?

Answer 1

Antonio Inoki was the opponent in question, and He was a wrestler, not a sumo.

it took place in Tokyo, March 1976 for which ali was paid a reported $6 million.

ali took a lot of damage to the legs, because Inoki signed a contract stating he wouldn't do this technique or that technique, so in the end all he could do was drop kick ali in the legs, which is what he did for 15 tedious rounds.
