The boxing world was left buzzing after Naoya Inoue’s lightning-fast destruction of Ramon Cardenas — a fight that ended with a stunning first-round knockout. But just as fans were hailing Inoue’s latest showcase of power and speed, boxing icon Floyd Mayweather stepped into the conversation, questioning the legitimacy of the knockout and igniting a firestorm of controversy.

Was it a clean KO? Did Cardenas go down too easily? And what does this mean for Inoue’s reputation? Here’s everything you need to know.

The KO That Shook the World

On fight night, expectations were high for Inoue, who came into the bout undefeated, undisputed, and widely considered the pound-for-pound king. Ramon Cardenas, while less decorated, was no pushover — a durable fighter known for his resilience and counter-punching.

But the fight didn’t even get a chance to develop. Less than two minutes in, Inoue unleashed a devastating left hook that sent Cardenas crumpling to the canvas. The referee counted him out, and the crowd erupted. Another name added to Inoue’s growing list of victims.

Or so it seemed.

Enter Floyd Mayweather

Shortly after the fight, Floyd Mayweather broke his silence in an explosive interview, casting doubt on the authenticity of the knockout. “I’ve been in the ring with killers,” Floyd said. “That punch didn’t look like it should’ve ended a world-class fighter’s night. I’m not saying it was fixed… but something doesn’t add up.”

Mayweather went on to question Cardenas’s reaction to the punch, noting how little resistance he showed during the fight. “Either the punch landed perfectly — and I mean surgically perfect — or Ramon wasn’t ready for this stage,” he added.

His comments immediately divided fans, with some accusing Mayweather of being jealous of Inoue’s rise, while others praised him for calling out what they saw as suspicious.

Breaking Down the Footage

In the days that followed, analysts broke down the footage frame-by-frame. The punch clearly landed flush, catching Cardenas on the jaw with full torque. The slow-motion replay revealed how Inoue had baited Cardenas into lowering his guard before firing the left hook — a textbook setup.

Still, skeptics remained. “Boxers don’t fall like that unless they’re truly hurt — or they don’t want to fight,” said one veteran trainer. Some online forums even suggested that Cardenas may have been overwhelmed by the stage and mentally checked out.

Cardenas Responds

Ramon Cardenas, in a post-fight statement, defended his performance: “Naoya Inoue is the hardest puncher I’ve ever faced. That shot caught me clean. I wasn’t out cold, but my legs weren’t under me. I couldn’t continue.”

He also addressed the rumors, saying, “Anyone who thinks I quit clearly doesn’t know what it’s like to stand in front of Inoue. Go try it and then tell me it was fake.”

Inoue Keeps It Classy

As for Inoue, the Japanese superstar kept his response short but respectful. “I trained for a war, but I’m happy with the result. Ramon is a tough fighter — it just ended quickly. That’s boxing.”

He declined to address Mayweather’s criticism directly, instead focusing on his goal to unify another weight class and continue his global dominance.

So, What’s the Truth?

Did Floyd have a point, or was this just another example of his trademark mind games? There’s no solid evidence to suggest foul play, and experts largely agree that the punch was legit. But Mayweather’s comments have added a new layer of intrigue to Inoue’s reign.

Whether you believe the knockout was clean or questionable, one thing is certain: Naoya Inoue continues to dominate, and now, even legends like Floyd Mayweather are paying close attention.
