Brock Lesnar Secretly Banned? Daniel Cormier Finally Reveals Why Their UFC Fight Was Silenced

In the world of mixed martial arts (MMA), very few hypothetical matchups have stirred as much intrigue, speculation, and frustration as the potential UFC fight between Brock Lesnar and Daniel Cormier. Fans were teased with a high-profile clash that could have rewritten the history books of combat sports. Yet, that fight never came to fruition, and for years, the real reason remained shrouded in mystery—until now.

Recently, Daniel Cormier broke his silence, offering a candid, no-holds-barred explanation about why the highly anticipated showdown with Brock Lesnar was quietly scrapped. As the story unfolds, it becomes increasingly clear that Lesnar’s departure from UFC wasn’t just a matter of timing or contract issues. Something deeper, something more unsettling, was at play—possibly even a secret ban that the UFC never wanted the public to know.

The Fight That Was Meant To Be

To understand the full impact of what was lost, we need to look back at the timeline. In 2018, Daniel Cormier, already a UFC Light Heavyweight Champion, defeated Stipe Miocic to become the UFC Heavyweight Champion. During his post-fight celebration, Brock Lesnar stormed the Octagon in dramatic fashion, shoving Cormier and igniting what looked like the beginning of a blockbuster rivalry.

Dana White, UFC President, appeared just as excited as the fans. The idea of pitting a two-division champion like Cormier against a global draw like Lesnar promised not only massive PPV buys but a true crossover moment for the sport. Lesnar, already a former UFC Heavyweight Champion and a legendary figure from the WWE, brought with him millions of fans from both wrestling and MMA.

Everything was seemingly in motion. White confirmed Lesnar was re-entering the USADA testing pool, a requirement for any returning fighter. Media outlets buzzed with updates and countdowns. Yet, weeks passed, then months, and then the buzz faded. The fight never happened.

Daniel Cormier Opens the Vault

For years, Daniel Cormier played it coy. He gave vague answers or blamed scheduling conflicts. But in a revealing interview in mid-2025, Cormier finally admitted what fans long suspected: the Brock Lesnar vs Daniel Cormier fight was never close to happening—not because of financial disagreements, but because Lesnar was quietly pushed out of the UFC picture.

According to Cormier, “There were forces at play that didn’t want Brock back in the cage. And it wasn’t just money. I think there were issues behind the scenes that made it impossible for UFC to go through with it. Whether you want to call it a soft ban or just a red flag, the end result was the same—Brock wasn’t coming back.”

This revelation sent shockwaves through the MMA world. For years, UFC executives had maintained that Lesnar simply decided to stay retired or that WWE commitments prevented the fight. But Cormier’s confession suggests there were internal concerns within the organization—perhaps legal, medical, or regulatory—that made Lesnar’s return untenable.

Was Brock Lesnar Secretly Banned from UFC?

The phrase “secret ban” is a strong one, but it’s not without precedent. UFC has a long history of keeping disciplinary actions under wraps unless legally required to disclose them. Fighters have been known to quietly disappear from rankings, removed from rosters without official suspension announcements.

With Lesnar, the signs were subtle but telling. His name vanished from the USADA testing pool database after only a few months, with no formal retirement notice. Dana White’s public tone shifted from enthusiasm to evasion whenever asked about Lesnar. Even the WWE, which usually cross-promotes its stars’ ventures into MMA, went radio silent.

There’s speculation among insiders that Lesnar failed multiple USADA tests, or perhaps worse—refused testing altogether. One source close to the UFC, speaking anonymously, suggested Lesnar’s presence posed “legal and branding risks” to the UFC as it expanded into new markets and corporate partnerships, particularly with ESPN and Disney.

While there’s no official documentation confirming a ban on Brock Lesnar, Cormier’s statements lend credibility to long-held fan theories. If true, UFC may have essentially blacklisted Lesnar without a formal process, allowing both sides to save face.

The USADA and WWE Loophole

One crucial element in this saga involves the U.S. Anti-Doping Agency (USADA). As a returning fighter, Lesnar was required to undergo six months of clean testing before competing. Back in 2016, when Lesnar faced Mark Hunt at UFC 200, he was given an exemption from this policy due to a late notice return. After winning the fight (which was later overturned), Lesnar tested positive for clomiphene, a banned substance.

The incident led to significant fallout. Hunt sued the UFC, claiming they knowingly allowed a doped-up Lesnar to fight. That lawsuit, still echoing in MMA circles, allegedly made UFC reluctant to take similar risks again—especially as they pursued lucrative broadcasting deals and attempted to shake the image of being a “Wild West” organization.

Daniel Cormier even hinted at this in his interview, stating, “After the Hunt case, I think UFC didn’t want to go through that storm again. Especially not with someone like Brock, who brings chaos wherever he goes—good or bad.”

It’s worth noting that WWE does not follow USADA protocols. Lesnar, as a part-time wrestler, was exempt from WWE’s own wellness policy. This created an awkward double standard, one that raised questions about fighter health and promotion integrity. For UFC, aligning with Lesnar again might have sent the wrong message at a time when the organization was striving for mainstream respectability.

Cormier’s Bittersweet Reflection

For Daniel Cormier, the fight with Lesnar represented more than a payday. It was a chance to headline one of the biggest spectacles in MMA history—a heavyweight bout between two champions from very different worlds. It could have cemented Cormier’s legacy and given fans the kind of superfight that rarely materializes.

“I trained like I was going to fight Brock. I really did,” Cormier shared. “We had dates. We had plans. And then everything just… stopped. Nobody would tell me why. It was like they ghosted the whole situation.”

The emotional tone in his voice revealed a deep-seated disappointment, not just as a fighter but as a competitor who wanted to test himself against the best. “It wasn’t about the belt, the money, or the hype,” he said. “It was about proving something. And that moment was stolen.”

The Fans’ Perspective: A Dream Deferred

Among fans, the fight’s cancellation felt like a betrayal. For many, Brock Lesnar vs Daniel Cormier was the perfect storm—athleticism, star power, and drama all wrapped into one. Social media lit up with speculation, memes, and frustration. Theories ranged from injury coverups to WWE politics, but none quite captured the quiet vanishing of one of UFC’s most marketable matchups.

Now, with Cormier’s revelation, fans finally have some closure—but also a deeper sense of what was lost. The fight would have likely broken PPV records and attracted crossover viewership from WWE’s global fanbase. It could have opened doors for more high-profile inter-promotional fights and bridged the gap between scripted and unscripted combat.

Where Does Brock Lesnar Stand Now?

Brock Lesnar, now in his late 40s, has shown no signs of returning to MMA. While still appearing sporadically in WWE, he’s largely stepped back from the public eye. His body has taken immense punishment over the years—from NCAA wrestling to UFC to decades of wrestling performance.

Yet his name still lingers in fight circles. Every time a heavyweight emerges, fans ask the inevitable: “Could he take Brock?” His legacy remains controversial but undeniable. Few fighters in history have brought as much mainstream attention to the UFC as Lesnar did.

But the reality is sobering: the door to UFC appears permanently closed. If a secret ban was in place, it would explain why he never negotiated a proper return. And in the wake of the Cormier interview, it’s unlikely UFC will be rushing to deny the claims.

The Future of Superfights and UFC Transparency

The Lesnar-Cormier saga serves as a cautionary tale about ambition, secrecy, and the business side of combat sports. It’s a reminder that not all fights are lost in the cage—some are lost in boardrooms, lawsuits, and private decisions made behind closed doors.

If anything, Cormier’s honesty could spark a broader discussion within the MMA community about transparency. Should fighters be informed when their potential opponents are quietly blacklisted? Should fans have the right to know when health or legal concerns dictate matchmaking?

As UFC continues to evolve into a global entertainment brand, balancing integrity with profitability becomes more complex. Fighters like Daniel Cormier, willing to tell the truth even years later, are vital to keeping the sport grounded.

Conclusion: A Fight That Will Live in Fantasy

Ultimately, the Brock Lesnar vs Daniel Cormier fight may live forever—not as a battle inside the Octagon, but as a “what if” whispered in gyms, forums, and fantasy matchups. Thanks to Cormier’s long-awaited revelation, we now know the fight was more illusion than reality.

Still, in a sport built on unpredictability, one lesson remains: silence often speaks louder than any punch. And in the silence surrounding Lesnar’s disappearance from UFC, we may have just uncovered one of the most quietly explosive stories in MMA history.
