One of the most controversial fights in boxing history.
Ali v Liston - 25th May 1965
Around about a minute into the bout Ali connecting with a quick, chopping right to Liston's head as Liston was moving toward him.
The moment ultimately ended the fight and became known as "the phantom punch" as most people ringside did not see it. Many claim that Liston had bet against himself and that he took a dive because as he owed money to the mafia, and some believe that fears for his safety from Nation of Islam extremists forced him to get the hell out of the entire situation quickly.
