(Tuesday, May 25, 1965, 10:30 p.m. EDT) — Muhammad Ali knocked out Sonny Liston in the first round of their world heavyweight title rematch tonight in Lewiston, Maine.

Ali’s victory generated controversy over whether he’d truly connected when he sent Liston crashing to the canvas with a right to the head, or whether it was a “phantom punch,” implying that the fight had been fixed.
