Andy Ruiz Jr. returns to the ring after over two years against Damian Knyba on September 4. is set to end a more than two-year layoff, stepping back into the ring against Polish heavyweight Damian Knyba. This significant heavyweight clash will headline “The Fight” series on Wednesday, September 4, live from the Prudential Center in Newark, New Jersey.
The bout marks Ruiz Jr.’s highly anticipated debut under his new Matchroom Boxing promotional deal. It will be broadcast co-exclusively in the United States on TNT, truTV, and DAZN, with a worldwide stream available on DAZN.
Ruiz Jr. readies Newark comeback after two-year absence
For Andy Ruiz Jr. (35-2-1, 22 KOs), who is 36 years old, this fight against Damian Knyba isn’t just a return; it’s a critical moment for a career defined by dazzling highs and frustrating lulls. His last appearance was a majority draw against Jarrell Miller in August 2024, capping a period of infrequent activity.
Ruiz Jr. famously burst onto the global scene in June 2019, securing one of boxing’s most shocking upsets by defeating Anthony Joshua for the unified heavyweight titles. He then lost those belts in a December 2019 rematch. Since then, “The Destroyer” has fought only three times this decade.
Victories came against Chris Arreola in May 2021 and Luis Ortiz in September 2022. Ruiz Jr. recently signed with Eddie Hearn’s Matchroom Boxing, a move that signals a renewed push for championship contention. Reports of Andy Ruiz Jr.’s comeback have been circulating, and this official announcement confirms those discussions.
A disciplined new chapter for Ruiz Jr.
The Matchroom deal represents a fresh start for Ruiz Jr., a chance to rebuild his career after a stagnant period. His goal is clear: to reclaim a world title. “I’m going to be fighting in Newark, New Jersey on September 4, baby,” Ruiz Jr. declared, expressing confidence.
“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.” His ambition remains undimmed, even after a lengthy absence from the ring.
Damian Knyba eyes upset in New Jersey
Standing opposite Ruiz Jr. will be Damian Knyba (17-1, 11 KOs), a 30-year-old Polish heavyweight known as “Polish Hussar.” He’s based in New Jersey, giving him a home-turf advantage at the Prudential Center, a venue he knows well.
Knyba’s professional debut came in June 2021, quickly stopping Petr Frohlich. He compiled an impressive 17-0 record before suffering his first professional defeat in January 2026, a third-round TKO to Agit Kabayel for the interim WBC title in Germany. Knyba, who signed a long-term promotional pact with Top Rank in January 2023, has a massive opportunity to make a statement.
Familiar territory for “Polish Hussar”
For Knyba, this fight is a chance to rebound from his sole professional loss and announce himself as a serious contender. At 6 ft 7 in with an 86-inch reach, his physical dimensions could pose problems for the more compact 6 ft 2 in Ruiz Jr.
The Prudential Center isn’t new to Knyba; he’s fought there three times previously. This familiarity provides a comfortable setting for him to showcase his skills against a big name. He also secured a technical knockout win against Emilio Salas at Madison Square Garden in December 2022.
“I can’t wait to be back at the Prudential Center, my second home,” Knyba stated, anticipating strong local support. “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.”
Mielnicki and Williams headline co-feature
The chief support bout promises fireworks in the middleweight division, featuring Vito Mielnicki Jr. (23-1, 13 KOs) against Austin “Ammo” Williams (20-2, 13 KOs). This matchup represents a significant step up for both promising fighters, vying for position in a competitive weight class.
Mielnicki Jr. will be returning to the venue where he made his professional debut in 2019. Like Ruiz Jr., Mielnicki Jr. recently signed with Matchroom. “Every fight is another chapter in my story, and I’m ready to write my biggest one yet,” Mielnicki Jr. affirmed.
A pivotal middleweight clash
Williams possesses the tools to seriously challenge Mielnicki Jr. This is a crucial fight for his trajectory. A strong showing against Mielnicki Jr. would help put Williams back in the conversation for top contenders in the division.
Newark prospect Zaquin Moses (7-0, 3 KOs) will also feature on the undercard, scheduled for his first eight-round contest. The middleweight division often sees pivotal clashes, and this fight between Mielnicki Jr. and Williams could elevate the winner significantly.
