The world of heavyweight boxing is once again in turmoil — and this time, it’s Jarrell “Big Baby” Miller who’s shaking the ring ropes. The controversial American heavyweight has issued a bold, no-holds-barred challenge to former unified champion Anthony Joshua, claiming he’s ready to end the British star’s career for good.

The challenge, delivered during an explosive interview with a major sports outlet, has sent shockwaves through the boxing community. “If Joshua’s got the guts, he’ll face me,” Miller said. “And when he does, I promise — it’ll be his last fight. I’ll retire him.”

A Rivalry Reignited

This isn’t the first time Miller and Joshua have locked horns — at least verbally. The two were originally scheduled to fight in 2019 at Madison Square Garden, but the bout was scrapped after Miller failed multiple drug tests. That fight was eventually replaced by Joshua vs. Andy Ruiz Jr., which resulted in Joshua’s first career loss.

Now, nearly five years later, Miller is back — louder, bolder, and more aggressive than ever. He claims Joshua has been ducking “real threats” and hiding behind safe matchmaking. “He knows I’m bad for business — bad for his business,” Miller taunted.

Joshua, who recently scored an impressive knockout victory over Francis Ngannou, has yet to respond publicly to Miller’s callout. But sources close to his camp say the idea of a grudge match against Miller isn’t off the table.

The Risk of Ruin

The prospect of a fight between Miller and Joshua is as tantalizing as it is dangerous. Miller, despite his layoff and controversies, remains an imposing figure in the heavyweight division. His size, relentless pressure, and psychological warfare make him a wild card — especially for a fighter like Joshua, who’s experienced both dizzying highs and humbling lows in recent years.

Boxing analysts are already debating whether this would be a smart move for AJ. “A fight with Miller would sell, no doubt,” said British boxing commentator Rob Ellis. “But it’s risky. If Joshua loses to someone like Big Baby — after everything he’s built back — it could derail everything. That’s why people are calling it a career-ending fight.”

On social media, fans are split. Some see Miller as a clown looking for relevance, while others believe the beef between him and AJ is exactly the kind of genuine rivalry boxing needs.

Redemption or Ruin?

For Miller, this fight represents more than just a paycheck — it’s a shot at redemption. Once considered a rising star in the division, his career was derailed by multiple failed drug tests that tarnished his image and cost him major fights. But now, he insists he’s clean, focused, and more dangerous than ever.

“I’ve been counted out, laughed at, written off,” Miller said. “But I’m still standing. And I want the guy who’s supposed to be the golden boy. I want Joshua.”

The big question: will Joshua accept the challenge? With talks of a potential Tyson Fury or Deontay Wilder fight still circulating, Miller’s offer might be tempting, especially with the built-in drama and history.

What’s Next?

Promoters are reportedly interested. The rivalry, the unfinished business, and the headline potential all make Miller vs. Joshua a marketable event — especially if staged in the U.S. or Saudi Arabia, where both fighters have significant fanbases.

Still, one fact remains: the stakes are incredibly high. For Miller, it’s a shot at legitimacy. For Joshua, it could be legacy or disaster.

Whether the fight materializes or not, one thing is clear — Jarrell Miller has stirred the pot. And now, all eyes are on Anthony Joshua to see if he’s willing to risk it all in what could truly be a career-defining — or career-ending — showdown.
