Andy Ruiz Jr’s Comeback Ends in Upset Loss to Damian Knyba
Andy Ruiz Jr’s comeback was supposed to be a reminder. Instead, it became a warning.
In his first fight for two years, the former heavyweight world champion was outworked, outlasted and, on the night, outdone by Poland’s Damian Knyba, who claimed a unanimous decision in New Jersey and a career-defining scalp to go with it.
The scorecards told their own story: 117-110, 114-113, 114-113 to Knyba at the Prudential Center. The upset was real, not rhetorical.
The night the legs went
For six rounds, Ruiz tried to shake off the rust that has clung to his career since that rematch defeat to Anthony Joshua in 2019. The hands were still quick in flashes, the instincts still there, but the sharpness that once shocked the world in Madison Square Garden came and went in brief bursts.
Then came the seventh.
Under pressure, Ruiz’s legs betrayed him. He hit the canvas, his body sagging as much from fatigue and timing as from the shot itself. The bell arrived like a lifeline, sparing him from a finish that would have rewritten the narrative from upset on points to full-blown knockout disaster.
Knyba didn’t rush. He didn’t need to. The Pole boxed with a disciplined, measured rhythm, keeping his jab honest, his feet calm, his tactics clear. Ruiz swung late, chasing the kind of momentum-changing moment that once belonged to him, but Knyba refused to give him the opening.
The Mexican, now 36, finished the fight with a black eye and a bruised ego, but not a broken will.
A champion searching for himself
Ruiz’s career since that glorious night against Joshua has been a stop-start story of injuries, layoffs and missed chances. The talent has never been in doubt. The continuity has.
This latest chapter came after another long spell out of the ring, and Ruiz did not hide from that reality.
“It was just a long lay-off, and it was a great opponent,” he said. “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.”
Those words carry weight. Ruiz has just signed with Eddie Hearn’s Matchroom, a move designed to relaunch a heavyweight run rather than close one down. This defeat complicates that plan, but it doesn’t kill it. Not yet.
He gambled on a dangerous opponent for a comeback bout and paid the price. The question now is whether he can afford another setback in a division that moves on quickly and forgets even quicker.
Knyba steps into the conversation
While Ruiz wrestles with his own future, Knyba walks away with something far more valuable than a famous name on his record: leverage.
He boxed with maturity, stuck to his strategy and showed the composure of a man who believes he belongs at the top table. The win immediately shifts him from prospect to genuine contender, and he wasted no time aiming high.
“I really want a rematch with Kabayel,” he said, calling out WBC heavyweight champion Agit Kabayel, the German who knocked him out earlier this year.
That defeat in Germany still burns. Now, armed with the Ruiz win, Knyba sees a path back to the man who beat him and, with it, a shot at the belt.
One man rebuilding. Another rising. Ruiz Jr once tore up the heavyweight script in a single night. Knyba has just written himself into the latest draft.
