Newark, NJ, USA - Damian Knyba scored the biggest victory of his career Friday night, dropping former unified heavyweight champion Andy Ruiz Jr. and earning a unanimous decision over 12 rounds at the Prudential Center in Newark, New Jersey.

The judges scored the fight 117-110, 114-113 and 114-113 for Knyba, who improves to 18-1 (11 KOs) and immediately puts himself back into the heavyweight conversation following his January loss to Agit Kabayel.
Ruiz falls to 35-3-1 (22 KOs), and at 36 years old, his options at the top of the division have narrowed considerably.
It was supposed to be the beginning of another run.
Instead, it became Knyba's night.
The physical contrast between the two heavyweights was obvious from the opening bell.
Ruiz had weighed in at a trim 254.3 pounds, his lightest weight in years, while the towering 6-foot-7 Knyba came in at 255.5 pounds.
Despite weighing virtually the same, they were completely different physical propositions.
Knyba immediately began using his considerable height and reach advantage, establishing the jab and forcing Ruiz to repeatedly cross distance before he could attack.
Ruiz targeted the body early and occasionally attempted to bring the right hand over Knyba's jab, but his offensive output was limited.
Knyba wasn't doing anything overly complicated.
He didn't need to.
He jabbed. He moved. He controlled range.
And when Ruiz managed to get close, Knyba frequently tied him up and forced the referee to separate them.
By the fourth round, Ruiz was already facing a problem. He was getting closer, but he wasn't consistently landing the combinations that have traditionally made him such a dangerous heavyweight.
Ruiz increased his activity in the fifth.
He landed rights on the inside, began targeting Knyba's body with more purpose and finally started finding opportunities to bring his faster hands into the fight.
Knyba was warned repeatedly for holding, and a cut developed around his left eye.
There were signs that Ruiz might finally be beginning to solve the puzzle.
Then came the seventh round.
It was the defining moment of the fight.
Knyba caught Ruiz clean and badly hurt the former champion before unloading with a sustained attack.
Ruiz appeared badly shaken as Knyba continued throwing.
Then Ruiz went down.
The knockdown transformed what had already been a strong performance by Knyba into something considerably more significant.
He wasn't merely frustrating Ruiz with his size.
He had hurt and dropped a former unified heavyweight champion.
Ruiz survived the round, but suddenly the comeback fight had become a fight for survival.
To Ruiz's credit, he responded.
Rounds eight and nine produced his best sustained work of the night.
Ruiz finally began forcing his way inside, landing heavy right hands over the top and attacking Knyba's body. The fight briefly came alive as Ruiz's combinations forced the Polish heavyweight backward.
Knyba increasingly looked to hold when Ruiz reached close range, while the crowd at the Prudential Center rallied behind the former champion.
For a moment, it appeared Ruiz might be mounting a dramatic comeback.
But it didn't last.
By the tenth round, Knyba had returned to the weapon that had served him so well all night.
The jab.
Ruiz's activity dropped again.
Knyba moved, jabbed and forced Ruiz to follow him around the ring. Even with the fight slipping away, Ruiz struggled to produce the sustained offensive urgency required to change it.
The eleventh was particularly damaging to Ruiz's hopes.
Knyba continued throwing while Ruiz simply wasn't doing enough.
Ruiz made one final attempt to increase the pressure in the twelfth, landing to the body and looking for his overhand right, but Knyba remained composed and made him miss repeatedly.
There would be no late rescue.
After 12 rounds, all three judges awarded the fight to Knyba.
This is an important victory for Damian Knyba.
His first professional defeat came earlier this year against Agit Kabayel, who has since become WBC heavyweight champion.
That loss could easily have sent Knyba back toward rebuilding fights.
Instead, the 30-year-old accepted another major assignment and defeated one of the most recognizable heavyweights of his generation.
And this wasn't simply a case of surviving Ruiz for 12 rounds and escaping with a decision.
Knyba implemented a clear tactical plan, controlled long stretches of the fight with his jab, frustrated Ruiz's attempts to close the distance and produced the fight's biggest moment when he dropped him in the seventh.
Knyba entered Newark at 17-1 with questions surrounding where he belonged in the heavyweight picture.
He leaves at 18-1 with a victory over Andy Ruiz Jr. on his record.
That's a very different position.
For Ruiz, the questions are considerably more difficult.
There were reasons for optimism entering Friday night.
Ruiz had reunited with trainer Manny Robles.
He had taken his conditioning seriously.
He weighed just 254.3 pounds after coming in at more than 274 pounds for his 2024 fight against Jarrell Miller.
His surgically repaired right hand was healthy enough to compete.
The problem was that none of it produced the performance Ruiz needed.
This wasn't an obviously out-of-shape Ruiz running out of gas.
He simply struggled to consistently close the distance against Knyba and didn't throw enough punches when the fight demanded urgency.
That makes the defeat harder to dismiss.
Ruiz had spoken before the fight about becoming a two-time heavyweight champion.
That road now looks extremely difficult.
He has fought only five times since losing the unified championship to Anthony Joshua in December 2019, and his record during that period now stands at two wins, two losses and a draw.
At 36, another lengthy rebuilding process makes little sense.
There will always be fights available to Andy Ruiz Jr. His name, his 2019 upset of Joshua and his place in heavyweight history guarantee that.
But meaningful options at the top of the division are another matter.
Friday night was supposed to establish that Ruiz remained a serious player in the heavyweight championship picture.
Instead, Damian Knyba took his opportunity.
And now it is Knyba—not Ruiz—who leaves Newark moving forward in the heavyweight division.
