Anthony Joshua is slated to face his long‑standing rival Tyson Fury later this year, but before that marquee clash he has agreed to a warm‑up bout against Kristian Prenga on July 25. The British heavyweight is coming back to the ring after a harrowing car accident that claimed the lives of two close friends, and the fight with Prenga is being framed as a chance to shake off any ring rust and ensure he is firing on all cylinders for the Fury showdown.

However, leading UK trainer Shane McGuigan has warned that this preparatory fight could be a serious misstep. McGuigan, who has worked with several top‑level fighters, told Sky Sports that a training camp is a solitary, demanding environment.

He argued that if a boxer is motivated solely by love of the sport and not by the financial rewards, the intensity of preparation may not be at the level it once was. “You need to bite into a real challenge,” he said, adding that the ultimate test for Joshua should be the fight with Fury, not a lower‑profile opponent.

The trainer also described Joshua as a “confidence fighter,” suggesting that the champion might feel the need for an extra win to boost his self‑belief. Yet McGuigan warned that the emotional toll of Joshua’s recent tragedy could make an additional camp without his usual support team a “horrible experience.” He speculated that the loss of friends and the trauma of witnessing a fatal accident could weigh heavily on the heavyweight’s mental state, potentially undermining his preparation.

According to McGuigan, the purpose of a warm‑up fight is often to give a boxer a controlled environment to test his conditioning and sharpen his skills. In Joshua’s case, however, the trainer doubts that a bout with Prenga will add any real value.

“It’s not going to make him a better fighter,” McGuigan said. “It will simply expose any cracks that already exist in his game.” He fears that the extra fight could highlight weaknesses rather than conceal them, leaving Joshua vulnerable heading into the high‑stakes clash with Fury.

The potential risk is not limited to Joshua. McGuigan noted that Fury might also consider taking an interim fight, which could further complicate the timeline for the long‑awaited showdown.

He suggested that Fury’s motivation might be to “wind them up,” implying that the British champion’s camp could be playing into a psychological game. Looking back, the two heavyweights have come close to meeting in the past.

In 2021, Joshua’s loss to Oleksandr Usyk derailed a possible undisputed title bout with Fury. McGuigan believes that if Fury were in Joshua’s position, he would have seized the opportunity immediately rather than opting for a warm‑up fight.

“They missed the first chance and would be foolish to miss it again,” he warned, pointing out the unpredictable nature of professional boxing, where injuries and head clashes can derail even the best‑laid plans. Beyond the physical preparation, McGuigan highlighted the mind‑games surrounding the fight. Decisions such as who will walk to the ring first, who will be billed as the A‑side or B‑side, and other promotional details are largely ego‑driven. He argued that these superficial concerns are irrelevant compared to what will happen in the 36 minutes inside the ropes.

“It all comes down to the action in the ring, not who gets the better poster or the first walk‑out,” he said. In summary, McGuigan’s assessment paints Joshua’s warm‑up bout as a potentially costly distraction. While a tune‑up fight can be useful for sharpening reflexes and testing new strategies, the unique emotional circumstances surrounding Joshua’s recent tragedy, combined with the looming magnitude of a Fury encounter, may render the extra contest more harmful than helpful.

The trainer urges the champion to focus on the core challenge: delivering a decisive performance against Fury when the two finally meet. Any additional fight risks exposing vulnerabilities, draining confidence, and diverting attention from the primary objective of securing a historic victory in the heavyweight division. The upcoming Prenga fight will be closely watched by fans and analysts alike, not only for its own merit but for the clues it may provide about Joshua’s readiness for the ultimate test. Whether McGuigan’s warnings prove prescient remains to be seen, but the stakes are undeniably high for both fighters as they inch toward what could become one of the most talked‑about heavyweight clashes in recent memory.
