Andy Ruiz Jr Stunned by Damian Knyba in Career-Defining Fight
The last time Andy Ruiz Jr ripped up the script, he walked out of Madison Square Garden with Anthony Joshua’s world titles and boxing’s heavyweight hierarchy in pieces. Seven years on, under the lights in New Jersey, he was on the wrong end of the upset.
Damian Knyba, the largely unheralded Polish heavyweight, seized the biggest night of his career with a disciplined, uncompromising performance to hand Ruiz a unanimous decision defeat at the Prudential Center on Friday.
The cards told the story of a fight that slipped away from the former champion and opened the door for a new contender: 117-110, 114-113, 114-113 in Knyba’s favour.
Ruiz floored, Knyba holds his nerve
For six rounds, Ruiz tried to shake off two years of inactivity with the tools that once shocked Joshua – fast hands, sharp counters, that compact, aggressive style. He found moments, especially when he closed the distance, but Knyba refused to be dragged into the kind of wild exchanges that made Ruiz a champion.
The turning point came in the seventh. Ruiz’s legs betrayed him, sending him to the canvas as Knyba’s pressure and size finally told. The Mexican beat the count and was rescued by the bell, but the damage on the scorecards was done. From there, he was chasing a fight that no longer belonged to him.
Ruiz rallied late, loading up and trying to drag Knyba into danger. The Pole stayed calm, stuck to his jab, used his height, and kept the former champion at arm’s length. Where others might have panicked under the weight of the name in front of them, Knyba stayed cold.
By the final bell, Ruiz wore a black eye and the frustration of a man who knew he had given away too many moments, too many rounds, to a hungrier opponent.
Ruiz vows to push on
This was Ruiz’s first outing since 2022, another stop-start chapter in a career repeatedly stalled by injuries and the fallout from his 2019 rematch loss to Joshua. At 36, with a fresh promotional deal under Eddie Hearn’s Matchroom banner, this was supposed to be the night he reminded the division he still mattered.
Instead, he walked away with a blemish on his comeback, but not on his belief.
“It was just a long lay-off, and it was a great opponent,” Ruiz said afterwards. “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.”
The risk backfired on the scorecards, but it underlined Ruiz’s intent: no tune-ups, no soft touches, just straight back into the deep end. The question now is how quickly he can return and how much this defeat dents his standing in an increasingly crowded heavyweight picture.
Knyba eyes revenge and a title path
For Knyba, this was more than a win over a former world champion. It was a statement that he belongs in the conversation. Beating Ruiz puts his name into the mix, but his sights are already set higher – and more personal.
With the Ruiz scalp secured, Knyba used his moment to call out WBC heavyweight champion Agit Kabayel, the German who knocked him out in Germany earlier this year.
“I really want a rematch with Kabayel,” he said, wasting no time.
That loss still hangs over his record. Now he holds a victory that gives him leverage, momentum, and a genuine argument for another crack at the man with the belt.
One heavyweight legend of recent years just took a step back. Another hopeful took a stride forward. The next move, for both Ruiz and Knyba, will say everything about where their stories go from here.
