Oleksandr Gvozdyk says his Zuffa Boxing run ended almost as fast as it started, with the former WBC light heavyweight champion claiming the promotion terminated his contract after his February stoppage loss to Radivoje Kalajdzic.
Gvozdyk made the claim in a new vRINGe interview, where the 39-year-old Ukrainian said the split came by email after he had already started gearing back up for a return. That is a brutal piece of business, even by combat sports standards. One loss, one rough seventh round, and the door apparently got slammed shut.
Gvozdyk said the clause was simple enough. If a boxer loses, the promoter can move on.
“They terminated the contract in February after the loss.”
“Every promoter has that option if a boxer loses.”
He added that people around the fight had praised the action afterward, which made the timing sting even more. Gvozdyk said he rested, began preparing again around May, then learned in April that an email had arrived ending the agreement.

Gvozdyk’s Zuffa Boxing Exit Adds Another Twist To Dana White’s Boxing Push
Gvozdyk’s Zuffa Boxing debut was not some lifeless stinker. He dropped Kalajdzic twice and appeared to be building a strong lead before the fight flipped sideways in round seven. Kalajdzic put him down, then forced the stoppage after another knockdown, turning what looked like a veteran showcase into a harsh reminder that boxing loves wrecking tidy plans.
The former champion’s career already had plenty of hard miles on it. Gvozdyk beat Adonis Stevenson in 2018 to win the WBC light heavyweight title, defended the belt, and later ran into Artur Beterbiev in a 2019 unification fight. He returned from retirement, lost a decision to David Benavidez in 2024, then took the Zuffa Boxing shot against Kalajdzic in February.
Gvozdyk also described Zuffa’s setup as much more rigid than the usual boxing promoter model. He said fighters had clear rules on gear, even down to underwear and sock colors, and compared the operation to military housing.
“With Zuffa, it feels like a barracks.”
He was not trashing the entire system, though. Gvozdyk said the tighter format also removed headaches because fighters did not have to invent every walkout and presentation detail themselves. That tracks with how Dana White has talked about boxing, where the UFC boss wants cleaner production, tighter matchmaking, and less of the old alphabet-belt chaos that keeps the sport eating itself.
The awkward part is what happens to older names who lose exciting fights. Zuffa Boxing has been selling a more direct, sport-first version of the game, but Gvozdyk’s exit shows there is still a cold business edge under the shine. The same company that has been pushing major title ambitions with fighters like Jai Opetaia can also move on fast when a veteran no longer fits the plan.
For Gvozdyk, the next step is unclear. At 39, with three defeats against Beterbiev, Benavidez, and Kalajdzic, he is no longer getting eased into anything. If he fights again, it will likely be because another promoter sees value in the name, the experience, and the fact that even in defeat, The Nail still made somebody sweat.
