Andy Ruiz Jr. has lost more than 20 pounds for his comeback, but slimming down at 36 after 25 months of inactivity does not guarantee that his old hand speed or combination punching will return.
Ruiz weighed 254.3 pounds for Friday night’s main event against Damian Knyba, who came in at 255.5. Matchroom Boxing released the official weights Thursday.
It is Ruiz’s lowest scale reading since he weighed 252 pounds for his July 2018 decision over Kevin Johnson. He was 28 then, active, and still climbing toward the biggest victory of his career. Eight years later, his body has been through extreme fluctuations, long layoffs, and the soft living that followed his 2019 upset of Anthony Joshua.
Two years ago, Ruiz came in at 274.4 pounds for his draw with Jarrell Miller, making this a drop of 20.1 pounds. He was 268 when he stopped Joshua, ballooned to 283 for the rematch, and registered 268.8 against Luis Ortiz in 2022.
The 254.3 pound reading will be sold as evidence of renewed discipline. It may be. Ruiz clearly did more than stroll through camp and hope his name would carry him. Losing that much weight at this stage of his career still brings questions about what the reduction took out of him.
Extra mass is not an automatic source of punch resistance, but Ruiz has spent most of his prime absorbing heavyweight shots with a much thicker body. Cutting down rapidly may leave less natural padding through his upper body and neck. That is worth watching against a 6’7″ opponent whose punches arrive from steep downward angles.
Ruiz also needs his right hand to survive a full fight. He fractured it against Miller and said the injury prevented him from throwing properly during the second half. The lower weight will mean little if he cannot release the three-punch combinations that made him dangerous at close range.
Knyba gives him openings. The Polish heavyweight often stands tall and does not possess elite lateral movement. Added quickness should allow Ruiz to work around the long guard with overhand rights, then dig shorter punches underneath. The danger comes when Knyba grabs him. Repeated clinches may drain Ruiz’s legs and prevent him from establishing the fast inside exchanges he needs.
There is also a difference between looking better on a scale and being restored as a fighter. Ruiz’s inactivity has taken away valuable years, while his reflex-dependent style requires timing that neither roadwork nor dieting can reproduce. At his best, he slipped shots at close range and answered with combinations before opponents recovered. That version has not been seen consistently since the first Joshua fight.
Ruiz faces vastly more pressure here than a fighter merely shaking off ring rust. Ruiz cannot afford another flat performance against an opponent selected to relaunch him. A cautious decision or exhausting struggle would damage his value as a future opponent for the leading names at heavyweight. At 36, there is not enough time for a lengthy rebuild.
The lower number is encouraging, but the fight will reveal what Ruiz lost along with those 20 pounds. A rejuvenated former champion may turn up in Newark. We may just as easily see an older fighter who worked hard to recreate a body from his twenties without recovering the fighter who once occupied it.
