Andy Ruiz Jr Stunned by Damian Knyba in New Jersey

The lights were supposed to shine on Andy Ruiz Jr’s rebirth. Instead, they framed the night Damian Knyba arrived.

In his first fight for two years, the former heavyweight world champion was outboxed, outworked and ultimately outpointed by the tall, composed Pole at the Prudential Center in New Jersey on Friday night, losing a unanimous decision that sends a jolt through the division.

The cards told the story: 117-110, 114-113, 114-113 in favour of Knyba.

The performance told an even sharper one.

Ruiz floored, Knyba unmoved

For Ruiz, the man who shocked Anthony Joshua seven years ago and briefly ruled the heavyweight world, this was meant to be the first meaningful step back towards the elite. Instead, he hit the canvas in the seventh round, his legs betraying him as much as any punch, and needed the bell to rescue him from a worsening crisis.

The knockdown changed the tone of the fight. Up to that point, Ruiz had been trying to close the distance, looking for those fast, heavy combinations that once ripped Joshua’s belts away. Knyba refused to panic. He stuck to his jab, kept the distance honest, and made Ruiz work for every inch.

The Mexican tried to rally late. He pressed, swung, hunted for the moment that might flip the narrative back in his favour. It never quite came. Knyba’s discipline held, his shape stayed tight, and the clock became another opponent Ruiz could not beat.

A bruised face, not a broken plan

At 36, with a black eye and a scorecard that went against him, Ruiz walked out of the ring marked but not defeated in spirit. The injuries that have dogged him since his rematch loss to Joshua in 2019 have slowed his rhythm and stalled his momentum, yet he refused to paint this as anything more than a painful step on a longer road.

“It was just a long lay-off, and it was a great opponent,” Ruiz said after the fight, leaning on honesty rather than excuses. He had recently signed with Eddie Hearn’s Matchroom and insisted he had chosen risk over comfort. “I didn't want to take an easy fight, so that's why I took Damian. He's a big guy. But we've got to take risks. I've still got it in me, man. I've just got to stay active and I want to fight again.”

That, in many ways, is the crux of his future. Activity. Sharpness. A heavyweight career cannot be managed in two-year bursts, not at this stage, not with this level of competition. Ruiz still owns the name, the story, the upset that made him famous. What he no longer owns is the benefit of time.

Knyba’s statement and a familiar target

While Ruiz wrestles with what comes next, Knyba walks away with the biggest win of his career and a clear idea of where he wants to go. He did not just beat a former champion; he handled the occasion, the pressure and the late surge with the composure of a man who believes he belongs in the title conversation.

He wasted little time making his intentions public. The Pole called out Agit Kabayel, the German and current WBC heavyweight champion, immediately after his victory.

“I really want a rematch with Kabayel,” he said, eyes already fixed beyond the ring he had just conquered.

There is history there. Knyba was knocked out by Kabayel in Germany earlier this year, a defeat that might have dented some fighters’ ambition. Instead, he used Ruiz as a springboard back towards the man who beat him and the belt he now holds.

One heavyweight rebuild took a hit in New Jersey. Another may just have begun in earnest.

The question now is simple: who reaches the summit again first – the former champion chasing lost time, or the challenger who just tore up the script?
