Whether Wilder remains capable of accomplishing anything inside the ring that’s worth discussing is debatable. That’s what his fight versus Derek Chisora is all about — learning if one of the most destructive punchers in boxing history has enough left in his right hand to knock out someone more formidable than Tyrrell Herndon, the opponent the former WBC heavyweight champion stopped in the seventh round of his last fight nine months ago.

Chisora has been knocked out four times and, like Wilder, is well beyond his physical prime. But the entertaining veteran has been effective enough in his last three fights, points victories over Gerald Washington, Joe Joyce and Otto Wallin, to thrust himself back into the spotlight.

At 42, Chisora (36-13, 23 KOs) seemingly has more left than Wilder, 40, entering what he repeatedly promised will be his final fight Saturday night. That’s why Wilder (44-4-1, 43 KOs) is an underdog in a 12-round main event DAZN will stream to subscribers of its Ultimate plan or on pay-per-view from O2 Arena in London.

Wilder himself has said this fight will teach him whether he can still compete at the championship level. It looked like those days were long gone, despite Wilder’s otherworldly power, in back-to-back losses to Joseph Parker and Zhilei Zhang in December 2023 and June 2024.

His highlight-reel knockouts and ability to sell a fight have nevertheless afforded Wilder another opportunity to try to save his career in an age-appropriate fight that will happen seven or eight years too late.

According to the old boxing axiom, power is the last thing to go for faded fighters, especially heavyweights. Wilder hasn’t recorded a knockout since he viciously took out Robert Helenius in the first round of their October 2022 bout at Barclays Center in Brooklyn.

We know Wilder doesn’t take punches particularly well anymore, as his knockout losses to Tyson Fury and Zhang proved. Avoiding another one will depend on whether he can still unload one of those devastating right hands on Chisora’s chin.

The WBO's immediate move last weekend, naming Moses Itauma its mandatory challenger after his spectacular KO of Jermaine Franklin, could create a predicament for champion Fabio Wardley if he defeats Daniel Dubois (22-3, 21 KOs) on May 9 in Manchester, England.

Unless Oleksandr Usyk changes his mind about boxing Wardley, the hard-hitting Brit could risk losing his WBO belt if he doesn’t fight Itauma in due time. Wardley (20-0-1, 19 KOs) and Itauma (14-0, 12 KOs) are friends, share trainer Ben Davison and don’t want to fight each other.

The emerging Itauma’s championship options might be limited to Wardley, however, because it is unlikely Usyk will fight the 21-year-old knockout artist, either. A third fight versus Tyson Fury would be a much more profitable option for Ukraine’s Usyk (24-0, 15 KOs), assuming The Ring/IBF/WBA/WBC champ and Fury win their upcoming bouts with Rico Verhoeven and Arslanbek Makhmudov.

Wardley-Itauma would do big business in England as well, which would further complicate matters if Usyk won’t fight either of them.

Keith Thurman naturally won’t want his career to end on the brutal beating he took from Sebastian Fundora.

At 37, however, the former WBA/WBC welterweight champion doesn’t have the time nor the desire to rebuild himself toward another meaningful fight. Even though Thurman is one of Al Haymon’s favorite fighters, it’d also be tough to justify investing more money in him when there’s very little evidence that he can compete with the best junior middleweights at this stage.

Thurman (31-2, 23 KOs) suggested his face looked worse than he felt following five-plus rounds of one-sided action, yet this was the most damage he has suffered since he made his pro debut in November 2007.

Thurman has long been one of the sport’s most unique thinkers and has various interests away from boxing. Here’s hoping he’ll thus take a more sensible approach to retirement than most fighters.

■ Tim Tszyu versus Errol Spence is exactly the type of fight both former champions should embrace next. Tszyu (26-3, 18 KOs) and Spence (28-1, 22 KOs), who hasn’t fought since Terence Crawford dismantled him in July 2023, are diminished versions of what they once were and therefore perfectly suited to test each other in what would be a marketable event, especially in Australia. Tszyu must first beat Albania’s Denis Nurja (20-0, 9 KOs) in a 10-rounder Saturday night at WIN Entertainment Centre in Wollongong, Australia.

■ Yoenli Hernandez (10-0, 9 KOs) is developing into the middleweight division’s version of another dangerous Cuban, Osleys Iglesias. The high-risk, low-reward proposition of fighting Hernandez, The Ring’s second-ranked middleweight contender, will send champions and top contenders in different directions and make it difficult for him to get a title shot until it’s mandated by one of the four sanctioning organizations. Hernandez battered Terrell Gausha in ways that the longtime contender hadn’t been beaten. Referee Allen Huggins prematurely stopped the action while Gausha remained on his feet in the fourth round in Las Vegas. The heavy-handed Hernandez’s expansive offensive repertoire and relentlessness made it impossible for even a crafty defensive fighter such as Gausha (24-6-1, 12 KOs) to properly protect himself. Hernandez also appeared massive once he rehydrated, which makes him even more imposing.

■ It’s puzzling and unfortunate that Iglesias isn’t getting more exposure worldwide. The heavily favored Iglesias (14-0, 13 KOs) – ranked second, behind only Canelo Alvarez, among The Ring’s super middleweight contenders – will headline another Eye Of The Tiger Management event Thursday night at Casino de Montreal. The explosive southpaw is scheduled to oppose Russia’s Pavel Silyagen (16-0-1, 7 KOs) for the vacant IBF 168-pound title Terence Crawford gave up when he retired in mid-December. Iglesias is a 13-1 favorite over Silyagen, according to FanDuel, in a fight that should demonstrate precisely why Alvarez and other established super middleweights won’t fight him.
