Dunn would start the fight on the front foot chasing Ali, who would land a number of overhand rights early. A pair of lefts from Dunn landed in the third; however, Ali scored a knockdown with a right later in the round. Dunn would taste the canvas twice more in the fourth and once early in the fifth before a windmilling right from Ali sent Dunn down for the fifth and final time, prompting referee Herbert Tomser to wave the contest off. The fight is remembered for being the last time Ali won by stoppage, and also for being the last time he knocked down an opponent. The punch Ali used to knockout Dunn was taught to Ali by
Taekwondo Grandmaster Jhoon Rhee. Rhee called that punch the "Accupunch", which he learnt from
Bruce Lee. Rhee was Ali's head coach for this Dunn fight. ==Aftermath==
