What is known as the 'Phantom/Anchor Punch', of the second match between Sonny Liston vs Muhammad Ali. Took place on May 25, 1965 in Lewistown, Maine.

To this day, the ending of the second Ali - Liston fight remains one of the most controversial in boxing history. Midway through the first round, Liston threw a left jab and Ali went over it with a fast right, knocking the former champion down on his back. Liston rolled over, got up on his right knee and fell on his back again. Many in attendance did not see Ali deliver the punch. The fight quickly descended into chaos. Referee Jersey Joe Walcott, a former World Heavyweight Champion himself, had a hard time getting Ali to go to a neutral corner. Ali initially stood over his fallen opponent, gesturing and yelling, "Get up and fight sucker"!

Ali was awarded a first round knockout victory.

I have watched a tape of this fight, in black and white of course. And I did see Ali deliver the fast right to Liston's face.
