<p style="line-height:1.38;margin-bottom:12pt;margin-top:12pt;">Ten finishes that stopped the sport in its tracks, from 91-second destructions to eighth-round masterplans.</p><p style="line-height:1.38;margin-bottom:12pt;margin-top:12pt;">Boxing lives for the knockout. The sport can produce 12 rounds of tactical chess, but nothing compares to the moment one punch changes everything.</p><p style="line-height:1.38;margin-bottom:12pt;margin-top:12pt;">Careers end, legacies are built, and entire <a href="https://www.sportsbet.com.au/huddle/boxing/news/boxing-weight-classes-guide">boxing weight divisions</a> get reshuffled in a split second.</p><p style="line-height:1.38;margin-bottom:12pt;margin-top:12pt;">Today, we are going to look at 10 of the greatest knockouts in boxing history. Not just the most violent, but the most significant, the ones that carried weight beyond the final count and that gained a permanent place into the rich history of this amazing sport.</p><p style="line-height:1.38;margin-bottom:12pt;margin-top:12pt;">&nbsp;</p><h2 style="margin-bottom:4pt;margin-top:18pt;">1. Mike Tyson KO1 Michael Spinks (June 27, 1988)</h2><p style="line-height:1.38;margin-bottom:12pt;margin-top:12pt;">Two undefeated heavyweights in one of the <a href="https://www.sportsbet.com.au/huddle/boxing/news/highest-paid-boxing-matches">richest boxing matches of all time</a> at that point. Which ended in just 91 seconds.</p><p style="line-height:1.38;margin-bottom:12pt;margin-top:12pt;">Tyson, who at that time was only 21 years old, was already holding the WBA, WBC and IBF belts and walked through Spinks like he wasn't there.</p><p style="line-height:1.38;margin-bottom:12pt;margin-top:12pt;">A left uppercut dropped Spinks for only the second time in his career. He got up at four. Then a right hand to the jaw put him down for good. Referee Frank Cappuccino didn't need long to count.</p><p style="line-height:1.38;margin-bottom:12pt;margin-top:12pt;">Spinks, a former light heavyweight champion who'd never lost, retired a month later. Tyson's aura of invincibility was never higher than it was that night in Atlantic City.</p><p style="line-height:1.38;margin-bottom:12pt;margin-top:12pt;">&nbsp;</p><h2 style="margin-bottom:4pt;margin-top:18pt;">2. Muhammad Ali KO8 George Foreman (October 30, 1974)</h2><p style="line-height:1.38;margin-bottom:12pt;margin-top:12pt;">The Rumble in the Jungle. Ali was 32, a massive underdog against the terrifying Foreman, who'd destroyed Joe Frazier and Ken Norton in a combined five rounds. Nobody gave Ali a chance.</p><p style="line-height:1.38;margin-bottom:12pt;margin-top:12pt;">Ali's rope-a-dope strategy, leaning against the ropes and absorbing Foreman's power shots while the champion punched himself out, looked suicidal at the time.</p><p style="line-height:1.38;margin-bottom:12pt;margin-top:12pt;">By round eight, Foreman was exhausted. Ali launched a right-left combination that sent Foreman spinning to the canvas. He didn't beat the count.</p><p style="line-height:1.38;margin-bottom:12pt;margin-top:12pt;">It's by far one of the most famous <a href="https://www.sportsbet.com.au/huddle/boxing/news/fastest-knockouts-boxing-history">quickest boxing knockouts</a> in boxing history, and it turned Ali from a great fighter into a sporting deity.</p><p style="line-height:1.38;margin-bottom:12pt;margin-top:12pt;">&nbsp;</p><h2 style="margin-bottom:4pt;margin-top:18pt;">3. Juan Manuel Marquez KO6 Manny Pacquiao (December 8, 2012)</h2><p style="line-height:1.38;margin-bottom:12pt;margin-top:12pt;">Four fights, years of rivalry, and it only took one punch to rewrite the whole story.</p><p style="line-height:1.38;margin-bottom:12pt;margin-top:12pt;">Pacquiao was winning. He was the younger, faster, more dynamic fighter, and through five rounds he looked like he'd take this one too.</p><p style="line-height:1.38;margin-bottom:12pt;margin-top:12pt;">Then Marquez, stepping backwards, timed a perfect counter right hand as Pacquiao lunged in. The Filipino superstar went face-first into the canvas, completely unconscious. He didn't move for several seconds.</p><p style="line-height:1.38;margin-bottom:12pt;margin-top:12pt;">Marquez had finally, definitively, answered the question that had haunted him across a decade of fights with Pacquiao. One punch made up for three disputed results.</p><p style="line-height:1.38;margin-bottom:12pt;margin-top:12pt;">&nbsp;</p><h2 style="margin-bottom:4pt;margin-top:18pt;">4. Sugar Ray Robinson KO5 Gene Fullmer (May 1, 1957)</h2><p style="line-height:1.38;margin-bottom:12pt;margin-top:12pt;">Gene Fullmer had beaten Robinson four months earlier to take the middleweight title. He was one of the toughest men to ever lace up gloves, a granite-chinned brawler who never went down.</p><p style="line-height:1.38;margin-bottom:12pt;margin-top:12pt;">Robinson dropped him with a single left hook in round five. Fullmer hit the canvas completely out, arms splayed, and didn't move for several seconds after the count.</p><p style="line-height:1.38;margin-bottom:12pt;margin-top:12pt;">It remains one of the most perfectly thrown punches in boxing history.</p><p style="line-height:1.38;margin-bottom:12pt;margin-top:12pt;">&nbsp;</p><h2 style="margin-bottom:4pt;margin-top:18pt;">5. Lennox Lewis KO2 Donovan Ruddock (October 31, 1992)</h2><p style="line-height:1.38;margin-bottom:12pt;margin-top:12pt;">Lewis was still building his name as a heavyweight when he met Ruddock, a feared puncher nicknamed "Razor" who'd gone deep with Tyson twice.</p><p style="line-height:1.38;margin-bottom:12pt;margin-top:12pt;">In round two, Lewis decked Ruddock three times and stopped him 46 seconds into round two.</p><p style="line-height:1.38;margin-bottom:12pt;margin-top:12pt;">It was a statement knockout. Lewis went from promising contender to genuine heavyweight threat in the space of one punch, and the performance put him on the path to an eventual world title.</p><p style="line-height:1.38;margin-bottom:12pt;margin-top:12pt;">&nbsp;</p><h2 style="margin-bottom:4pt;margin-top:18pt;">6. Antonio Tarver KO2 Roy Jones Jr (May 15, 2004)</h2><p style="line-height:1.38;margin-bottom:12pt;margin-top:12pt;">Roy Jones Jr spent the better part of a decade looking untouchable. He was faster, more athletic, more creative than anyone in his weight class.</p><p style="line-height:1.38;margin-bottom:12pt;margin-top:12pt;">Then Tarver hit him with a single left hook in round two and Jones collapsed.</p><p style="line-height:1.38;margin-bottom:12pt;margin-top:12pt;">The image of Jones, one of the most gifted boxers of his generation, lying flat on his back with his eyes open and his body unresponsive, changed the way people viewed his career overnight.</p><p style="line-height:1.38;margin-bottom:12pt;margin-top:12pt;">Jones had moved up to heavyweight and back down to light heavyweight, and the weight drain had clearly taken a toll. But nobody expected it to end like that.</p><p style="line-height:1.38;margin-bottom:12pt;margin-top:12pt;">&nbsp;</p><h2 style="margin-bottom:4pt;margin-top:18pt;">7. Thomas Hearns KO2 Roberto Duran (June 15, 1984)</h2><p style="line-height:1.38;margin-bottom:12pt;margin-top:12pt;">Duran had "hands of stone." He was one of the most durable and feared fighters in boxing history.</p><p style="line-height:1.38;margin-bottom:12pt;margin-top:12pt;">Hearns hit him with a right hand in the second round that sent Duran face-first into the canvas. Duran tried to push himself up but his body wouldn't cooperate.</p><p style="line-height:1.38;margin-bottom:12pt;margin-top:12pt;">The knockout was jarring because Duran simply didn't go down like that.</p><p style="line-height:1.38;margin-bottom:12pt;margin-top:12pt;">Hearns' right hand remains one of the most devastating single punches in middleweight history, and it earned him the WBC super welterweight title.</p><p style="line-height:1.38;margin-bottom:12pt;margin-top:12pt;">&nbsp;</p><h2 style="margin-bottom:4pt;margin-top:18pt;">8. Manny Pacquiao KO2 Ricky Hatton (May 2, 2009)</h2><p style="line-height:1.38;margin-bottom:12pt;margin-top:12pt;">Hatton came in as the bigger man and a genuine world-level fighter. It didn't matter. Pacquiao was operating on a different plane entirely, landing shots from angles Hatton couldn't see coming.</p><p style="line-height:1.38;margin-bottom:12pt;margin-top:12pt;">The finish came in round two. Pacquiao threw a short left hand that caught Hatton clean on the jaw, and the Englishman fell backwards, unconscious before he hit the canvas.</p><p style="line-height:1.38;margin-bottom:12pt;margin-top:12pt;">He lay motionless for several seconds. It was the kind of knockout that effectively ends a career, and Hatton was never the same fighter afterwards.</p><p style="line-height:1.38;margin-bottom:12pt;margin-top:12pt;">&nbsp;</p><h2 style="margin-bottom:4pt;margin-top:18pt;">9. Julian Jackson KO4 Herol Graham (November 24, 1990)</h2><p style="line-height:1.38;margin-bottom:12pt;margin-top:12pt;">Graham was boxing beautifully. He was outclassing Jackson on points, making the feared puncher miss repeatedly, and looked headed for a comfortable victory.</p><p style="line-height:1.38;margin-bottom:12pt;margin-top:12pt;">Then Jackson landed one right hook.</p><p style="line-height:1.38;margin-bottom:12pt;margin-top:12pt;">Graham went down as if he'd been hit by a truck. The contrast between Graham's dominance in rounds one through three and the sudden, violent ending is what makes this knockout endure.</p><p style="line-height:1.38;margin-bottom:12pt;margin-top:12pt;">Jackson was one of the hardest punchers, pound for pound, in boxing history, and this was his signature moment.</p><p style="line-height:1.38;margin-bottom:12pt;margin-top:12pt;">&nbsp;</p><h2 style="margin-bottom:4pt;margin-top:18pt;">10. Deontay Wilder KO7 Luis Ortiz II (November 23, 2019)</h2><p style="line-height:1.38;margin-bottom:12pt;margin-top:12pt;">Ortiz was winning the rematch. He was outboxing Wilder, landing cleaner shots, and building a lead that had the commentary team questioning whether Wilder had an answer. He did.</p><p style="line-height:1.38;margin-bottom:12pt;margin-top:12pt;">In round seven, Wilder threw a short right hand that Ortiz didn't see and the Cuban crumbled instantly.</p><p style="line-height:1.38;margin-bottom:12pt;margin-top:12pt;">It was a reminder that Wilder's right hand is unlike anything else in modern heavyweight boxing. You can win every round against him and it doesn't matter if he lands that one shot. If you're looking to <a href="https://www.sportsbet.com.au/betting/boxing">bet on boxing</a>, understanding knockout power like Wilder's is essential when assessing the odds.</p>
