Former heavyweight champion Andy Ruiz Jr. is set to return to the ring after a two-year hiatus, facing Polish contender Damian Knyba on Sept. 4, 2026, at the Prudential Center in Newark, New Jersey. The fight headlines the third installment of TNT Sports and DAZN's monthly "The Fight" series and marks Ruiz's debut under his new promotional deal with Matchroom Boxing. For Ruiz, this bout represents a crucial opportunity to re-establish himself among the heavyweight elite, a division that has largely moved on without him since his stunning upset of Anthony Joshua in June 2019.

Ruiz first became a household name when he dropped Joshua four times en route to a seventh-round TKO at Madison Square Garden. That victory, one of the biggest upsets in boxing history, made Ruiz the first Mexican-American heavyweight champion. However, the fairytale quickly soured. In the rematch six months later, Joshua outboxed Ruiz over 12 rounds, reclaiming his belts and exposing the Mexican-American's conditioning and discipline issues. Since then, Ruiz has fought only three times: a uninspired decision win over an aging Chris Arreola in May 2021, a close decision against Luis Ortiz in September 2022, and a disappointing majority draw with Jarrell Miller in August 2024. The Miller fight, in particular, raised questions about Ruiz's commitment, as he appeared sluggish and lacked the explosiveness that had defined his career.

According to promoter Eddie Hearn, Ruiz battled a broken thumb during the Miller fight and struggled with personal problems that contributed to his inactivity. After a brief stint training with Eddy Reynoso, the coach of Canelo Alvarez, Ruiz has reunited with Manny Robles, the man who guided him to the Joshua upset. Robles' return to Ruiz's corner has sparked optimism, and Ruiz has been vocal about his desire to reclaim a world title, especially after Oleksandr Usyk vacated his belts earlier this year. "I'm going to be fighting in Newark, New Jersey on September 4, baby," Ruiz said in an official Matchroom press release. "After we get this victory, I would love to fight all the guys that have the belts Oleksandr Usyk vacated, and we're going to become a two-time champion next year, let's get it."

Ruiz's opponent, Damian Knyba, is a 6-foot-7 Polish heavyweight who is coming off his first professional defeat. Knyba lost by third-round stoppage to newly crowned WBC champion Agit Kabayel in January 2026. Despite the loss, Knyba is younger, naturally bigger, and has been far more active than Ruiz. For Knyba, the fight represents an immediate opportunity to re-enter the title picture, and he believes the Prudential Center will feel like a second home. "I can't wait to be back at the Prudential Center, my second home," said Knyba in the release. "I'm excited to be back in the ring in front of the New Jersey and New York fans, and they will fill the seats with white and red."

Knyba's size and youth present a real danger for Ruiz. At 36, Ruiz has often struggled against taller, longer fighters who can keep him on the end of their jabs. Joshua did it in the rematch, and even the 40-year-old Luis Ortiz was able to give Ruiz problems by using his reach. Knyba, though less experienced, possesses a similar physical advantage and will be highly motivated to derail Ruiz's comeback. However, Ruiz's hand speed and power remain his greatest assets. If he can get inside and land his signature combinations, he could stop Knyba and reignite his career.

The stakes are enormous for Ruiz. Another flat performance, or worse, a defeat, would make it difficult to justify his ambition of challenging for a heavyweight title. Promoter Eddie Hearn, who recently signed Ruiz to Matchroom, has expressed confidence that the former champion can return to form. "I think he's gonna be a massive threat to the division," Hearn told iFL TV. "He's got a massive fanbase, he's a huge name, he's a very, very good fighter, and we all know with Andy Ruiz, he's serious." Hearn also believes that Ruiz is motivated in a way he hasn't been since the first Joshua fight. "I've always liked him. I think he's a great guy, but he's struggled with consistency. But what I see right now, looking in his eyes, is someone who wants it bad," said Hearn.

Ruiz's motivation for a title run is clear, and he has made no secret of his desire for a third fight with Anthony Joshua. After earning roughly $7 million in their first meeting and another $13 million in the rematch, the financial appeal of completing the trilogy would be another big bag for both Joshua and Ruiz. But first, Ruiz must prove that he is still a relevant force in a division that now includes champions like Agit Kabayel, Daniel Dubois, and others. An impressive victory on September 4 could put him back into the conversation, but he will need to show that the old fire is still there.

The heavyweight division has seen many comebacks over the years. Fighters like George Foreman and Evander Holyfield returned to win titles after long layoffs, but they did so with discipline and a clear plan. Ruiz's path is less certain. His weight has fluctuated dramatically throughout his career, and his dedication to training has often been questioned. Against Knyba, he will need to prove that he can still handle a young, hungry contender who has nothing to lose. A win would set up a potential fight with the winner of the upcoming Dubois-Kabayel unification bout, or perhaps a matchup with the winner of the Joshua-Fury negotiations that have been rumored for late 2026.

For now, all eyes are on September 4. Ruiz has the chance to write a new chapter in his story, one that began with a shocking victory and meandered through inconsistency and injuries. If he can stop Knyba in impressive fashion, the boxing world will once again take notice. If he struggles, the comeback will be short-lived. The ball is in Ruiz's court, and the heavyweight division is watching.
