Damian Knyba upsets Andy Ruiz Jr. with unanimous decision win in Newark

Andy Ruiz Jr. Once stunned the sporting world in June 2019 as the first heavyweight champion of Mexican descent to defeat Anthony Joshua. The reality of his current standing was laid bare at the Prudential Center in Newark, New Jersey, where he suffered a unanimous decision loss to Damian Knyba.

The result serves as a significant setback for Ruiz's attempt to return to the heavyweight title picture. While the former unified champion entered the bout aiming to restart his championship ambitions under a new promotional deal with Eddie Hearn and Matchroom Boxing, he instead fell to an opponent who had been stopped in his own previous outing.

Physical Disparity and Tactical Execution

The fight was defined by a stark physical contrast. Knyba, standing 6-foot-7 with an 86-inch reach, leveraged these dimensions to keep the 6-foot-2 Ruiz at a distance from the opening bell. According to Ibtimes, Knyba used his lead hand to prevent Ruiz from closing the gap necessary to work effectively on the inside.

Ruiz struggled to solve this distance, and by the fourth round, Ringside24 reports his face was already marked by repeated straight shots. Whenever Ruiz managed to penetrate the perimeter, Knyba frequently tied him up in clinches to stall his offensive output.

Damian Knyba	6'7"	86 inches	18-1 (11 KOs)
Andy Ruiz Jr.	6'2"	Not Specified	35-3-1 (22 KOs)

Ruiz pointed to this holding as the primary reason he could not land his signature combinations. "I think it was just him holding. Every time I try to come in, he hold me really tight. And I couldn't let my combinations go,"Andy Ruiz Jr., via Ibtimes

The Turning Point and Recovery

The bout shifted decisively in the seventh round. Knyba landed a double jab-cross combination followed by a barrage of power punches that dropped Ruiz. The former champion was left badly shaken and had to survive a difficult stretch before the bell saved him.

However, Boxinginsider noted that hurting Ruiz appeared to motivate him, as the former champion landed hard and effectively throughout the eighth round. Ruiz also found success in the fifth and sixth rounds, where he increased his pace and opened a cut near Knyba's left eye.

These rallies were insufficient to overcome Knyba's disciplined boxing. In the 10th and 11th rounds, Knyba resumed a slower pace and relied once again on the jab, a strategy that minimized Ruiz's ability to perform. Ruiz was unable to secure a knockdown or a finish in the 12th round to close the gap on the scorecards.

The "Father Time" Debate

The loss brings scrutiny to Ruiz's consistency and conditioning. Since losing his titles to Anthony Joshua in late 2019, the seven-year period has been characterized by inactivity and weight fluctuations. This fight was his first appearance in more than two years, following a majority draw against Jarrell Miller in August 2024.

While Ruiz entered the ring at his lightest weight in years, the result prompted two former world champions serving as broadcast analysts to suggest he should consider stepping away from the sport. This perspective contrasts sharply with Ruiz's own insistence that he remains an elite competitor.

Ruiz attributed the defeat to the lengthy layoff rather than a permanent decline in ability. "Of course I [believe I can win a title], man. It was just a long layoff and it was a great opponent,"Andy Ruiz Jr., via Middleeasy

For Knyba, the victory is a professional reset. After his January stoppage loss to Agit Kabayel, he was in a must-win position. By defeating a former unified champion, he has repositioned himself in the heavyweight division and immediately called for a rematch with Kabayel.

Future Ramifications

The defeat complicates the strategic goals of Matchroom Boxing. The partnership with Ruiz was designed to guide him toward a second heavyweight championship run, yet the first bout of the deal resulted in a unanimous decision loss. The judges' scores—117-110, 114-113, and 114-113—highlight a performance that left Ruiz unable to meaningfully threaten Knyba's control.

Beyond the main event, the Newark card saw other results, including Vito Mielnicki Jr. Defeating Austin Williams via unanimous decision (98-91). In the lightweight division, Eridson Garcia claimed the WBO Latino title by stopping Alan Chaves, while Zaquin Moses defeated Angel Antonio Contreras.

The immediate future for Ruiz depends on whether Matchroom pursues a financially incentivized rematch with Knyba to salvage the comeback campaign or if the former champion is forced to accept he is no longer a viable title contender.

Undercard Upsets and Divisional Shifts

The main event was the centerpiece of a broader evening of results at the Prudential Center. While the heavyweight clash highlighted a struggle for momentum, other bouts on the card delivered definitive finishes. Eridson Garcia secured the WBO Latino lightweight title by stopping Alan Chaves, a victory that included dropping Chaves four times. In the super featherweight division, Zaquin Moses defeated Angel Antonio Contreras, who remained on his stool after the fifth round.

The Newark card also featured a middleweight contest where Vito Mielnicki Jr. Overcame Austin Williams. All three judges scored that bout 98-91 in favor of Mielnicki Jr.

According to Ibtimes, the result leaves Ruiz with a professional record of 35-3-1 with 22 knockouts. This marks only the third loss of his career, yet it comes at a time when he is turning 37 in one week. The Polish heavyweight, meanwhile, improved his record to 18-1 with 11 knockouts, although Yardbarker reports Knyba's record as 19-1.

The victory fundamentally alters Knyba's trajectory after his third-round stoppage loss to Agit Kabayel in January. Having successfully navigated a must-win situation, Knyba immediately called for a rematch with Kabayel. Ruiz, despite the defeat, expressed a desire to "run it back" and do things differently in a potential rematch with Knyba.

For Ruiz, the immediate priority is overcoming the effects of a two-year layoff. While he remains insistent that he has the ability to win another title, the outcome of the Newark bout complicates his path back to the elite level. Given the financial investment Matchroom Boxing has placed in his comeback, a rematch with Knyba is identified as the next step for both fighters.
