Fun story, Ali thought the bout was supposed to be a pro-wrestling predetermined kind of thing, but Antonio Inoki really wanted to fight. This miscommunication was only discovered 6 days before the bout.
A list of rules were placed on Inoki, prohibiting him from kicking unless he had one knee on the ground. Inoki pummelled Ali’s leg for 15 rounds in what was declared a draw.
The limited moves really prevented much action, but the impacts the bout had on Ali were very real.
