Newark, NJ, USA - Former unified heavyweight champion Andy Ruiz Jr. returns from another lengthy absence on Friday night, but there will be no gentle introduction back into the heavyweight division.
Andy Ruiz Jr. (35-2-1, 22 KOs) faces towering Polish heavyweight Damian Knyba (17-1, 11 KOs) over 12 rounds at the Prudential Center in Newark, New Jersey, with Ruiz attempting to launch what could be his final serious run toward another world championship.
Ruiz has not fought since his August 2024 majority draw with Jarrell Miller. He is now 36, has undergone surgery on the right hand he injured against Miller and has competed only four times since losing his heavyweight titles back to Anthony Joshua in December 2019.
Yet the talent that once carried Ruiz to one of the biggest heavyweight upsets in modern boxing has never really been in question.
The question Friday night is how much of it remains.
And Knyba is a legitimate opponent with which to find out.
It has now been more than seven years since Ruiz shocked the boxing world by dropping Anthony Joshua four times and stopping the previously unbeaten champion at Madison Square Garden.
For one remarkable night, Ruiz's combination of hand speed, timing, durability and counterpunching overwhelmed a much taller, more conventionally athletic heavyweight.
What followed has been considerably less remarkable.
Ruiz lost the immediate rematch to Joshua six months later, defeated Chris Arreola in 2021 and Luis Ortiz in 2022, then disappeared for almost two years before returning against Jarrell Miller in August 2024.
Ruiz started well against Miller, using his superior hand speed to land combinations, but his output declined as the fight progressed and Miller increasingly imposed himself. The fight ended in a majority draw.
There was an important complication: Ruiz suffered a significant injury to his right hand during the fight and subsequently underwent surgery.
Now comes another two-year absence.
Ruiz has reunited with trainer Manny Robles, who was in his corner for the first Joshua fight, and recent training footage has shown a noticeably leaner-looking former champion.
Those are encouraging signs.
But training footage cannot reproduce what happens when a 6-foot-7 heavyweight is throwing a jab at your face and refusing to stand where you want him.
Damian Knyba represents an interesting choice for Ruiz's return.
The 30-year-old Polish heavyweight is enormous, relatively mobile for his size and comfortable working behind a long jab. He has also already experienced what it is like to share the ring with one of the best heavyweights in the world.
Knyba suffered his first professional defeat in January when he faced Agit Kabayel for the WBC Interim heavyweight title in Germany.
The official result — a third-round stoppage — does not tell the entire story.
Knyba started well. He used his reach, landed clean punches and opened a cut around Kabayel's right eye before the German began closing the distance, attacking the body and overwhelming him with sustained pressure.
Kabayel ultimately took control quickly, but Knyba did enough early to demonstrate that he was not hopelessly out of his depth against elite opposition.
There is also considerably less stigma attached to that defeat now.
Kabayel has since become WBC heavyweight champion and has established himself firmly among the division's elite.
Knyba lost to an excellent heavyweight.
Now he gets another opportunity against a former champion whose current level is far less certain.
The physical contrast will be obvious from the opening bell.
Knyba stands approximately 6-foot-7. Ruiz is around 6-foot-2.
For Knyba, the strategy should be straightforward: establish the jab, force Ruiz to repeatedly cross open space and make the older fighter work before he can get into combination range.
For Ruiz, simply following Knyba around the ring will not be enough.
At his best, Ruiz was exceptionally good at shortening the distance against taller heavyweights. He could slip a jab, take a small step forward and suddenly unleash three or four punches before his opponent could reset.
That ability remains the key to this fight.
Watch Ruiz's feet.
If he is moving efficiently, slipping Knyba's jab and arriving in punching range with his balance underneath him, his superior hand speed should become a major problem for Knyba.
If Ruiz is reaching with single punches from too far away and repeatedly having to reset, the fight becomes considerably more difficult.
Fast hands are only useful when they are close enough to land.
Ruiz's weight has followed him throughout his career, sometimes unfairly and sometimes for very legitimate reasons.
He has never needed the physique of a conventional heavyweight. His unusual combination of mass, balance and hand speed is part of what makes him effective.
But there is a difference between being naturally heavy and being poorly conditioned.
That distinction could be particularly important Friday night.
Ruiz may have to repeatedly chase a 6-foot-7 opponent over as many as 12 rounds. He cannot afford to spend long stretches inactive and expect Knyba to voluntarily enter his preferred range.
Recent footage suggests Ruiz has lost considerable weight during camp, but the official weigh-in will provide a much better indication of his physical preparation.
Too heavy and the concern becomes stamina and mobility.
Too light and Ruiz risks sacrificing some of the physical strength that has always complemented his speed.
The ideal version of Ruiz has never been the lightest version.
It has been the conditioned version.
There is another unknown that cannot be answered until the fight begins.
Ruiz injured his right hand against Miller badly enough to require surgery.
For a fighter whose offense relies heavily on rapid combinations, confidence in that hand matters enormously.
The first hard right hand Ruiz throws may therefore be revealing.
Does he commit to it?
Does he immediately follow it with another punch?
Does he continue throwing it throughout the fight without hesitation?
A surgically repaired hand can be medically healed while a fighter remains psychologically reluctant to fully trust it.
Against Knyba, Ruiz cannot afford to become a predominantly left-handed fighter.
Knyba enters the fight having spent significant time in high-level heavyweight surroundings.
During his preparation, the Polish contender has worked extensively around former two-time heavyweight champion Anthony Joshua, including sparring during Joshua's training camps.
That does not automatically prepare someone for Ruiz's unusual style — Joshua and Ruiz are completely different fighters — but it does mean Knyba has spent significant rounds dealing with world-class heavyweight speed, power and intensity.
He also knows precisely what this opportunity represents.
A victory over Ruiz would instantly erase much of the damage caused by the Kabayel defeat.
Knyba would go from a heavyweight attempting to rebuild after his first loss to a contender holding a victory over a former unified world champion.
There may be considerably more at stake for Knyba than his relatively modest profile suggests.
The location is also well chosen.
Knyba has fought at the Prudential Center several times and enjoys considerable support from the large Polish-American boxing community in the New York-New Jersey region.
Ruiz, meanwhile, remains one of the most recognizable Mexican-American fighters in boxing and should bring substantial support of his own.
Knyba has already predicted that Polish supporters will fill the arena with red and white.
That combination could create an unusually lively atmosphere for a heavyweight fight that does not involve a current world title.
Every Ruiz combination could bring one section of the arena to its feet.
Every clean Knyba right hand could bring an immediate response from another.
By the time the heavyweights enter the ring, Newark could be loud.
Ruiz has made his objective clear.
He wants another heavyweight championship.
The breakup of the undisputed championship picture has created opportunities throughout the division, and Ruiz believes he can take advantage.
But at 36, he no longer has time for a prolonged rebuilding process.
A convincing victory over Knyba puts his name immediately back into the heavyweight conversation.
Another 18-month or two-year disappearance cannot follow.
If Ruiz truly intends to become champion again, Friday night needs to be the beginning of sustained activity rather than another isolated comeback appearance.
A defeat would be considerably more damaging.
Losing to Joshua was understandable.
Drawing with Miller after suffering a hand injury could be explained.
Losing to Knyba after another two-year absence would make another championship run extremely difficult to justify.
For Ruiz, this is not simply a return.
It is a test of whether there is still a serious heavyweight contender underneath one of the division's most recognizable names.
Knyba does not need to reinvent himself.
He needs discipline.
Keep Ruiz outside.
Jab constantly.
Make Ruiz reset.
Use the right hand when Ruiz begins reaching.
Tie him up when he gets inside.
Most importantly, Knyba cannot retreat in straight lines toward the ropes and allow Ruiz to plant his feet.
That is where Ruiz becomes dangerous.
Once Ruiz gets close enough to throw combinations without moving his feet, very few heavyweights can match his hand speed.
Knyba's best chance may actually come during the middle rounds.
If Ruiz begins strongly but his activity drops — as it did against Miller — Knyba's size could become increasingly difficult to overcome.
A 6-foot-7 heavyweight does not become smaller when his opponent gets tired.
Ruiz needs to make Knyba uncomfortable from the beginning.
Not reckless pressure.
Intelligent pressure.
Slip the jab.
Attack the body.
Force Knyba backward.
Make the taller fighter exchange at distances where his reach becomes less useful.
Kabayel provided a useful blueprint in January. Once he consistently got underneath Knyba's punches and began attacking the body, the complexion of the fight changed quickly.
Ruiz is not Kabayel.
He does not apply pressure in quite the same relentless manner.
But Ruiz possesses something Kabayel does not: extraordinarily quick combinations for a heavyweight.
If Ruiz can consistently get himself into range, Knyba may find the speed difference startling.
There are enough unknowns surrounding Ruiz to make this considerably more interesting than an ordinary comeback fight.
Two years away.
A repaired right hand.
Questions about conditioning.
A 6-foot-7 opponent.
And a 36-year-old former champion attempting to prove that his career still has another meaningful chapter.
Knyba should have success early.
Expect the Pole to establish his jab and make Ruiz spend some time figuring out the distance. Ruiz may look rusty during the opening rounds, particularly if Knyba stays disciplined and refuses to engage unnecessarily.
But if Ruiz is properly conditioned and the right hand is healthy, his speed and experience should gradually begin to tell.
Once Ruiz starts getting underneath the jab and forcing Knyba into exchanges at mid-range, the matchup changes significantly.
Knyba is dangerous enough to expose a diminished Ruiz.
The question is whether Ruiz is actually diminished.
Friday night should give us the answer.
Prediction: Andy Ruiz Jr. by late stoppage or clear decision.
