Oleksandr Usyk could lose to one of the most dangerous fighters in boxing, according to a heavyweight star

Untouchable throughout his professional career, Oleksandr Usyk may have a potential threat to his gleaming run in the sport if he ever gets matched against another lethal finisher.

Scoring career win number 24 just weeks ago, Usyk made light work of Daniel Dubois with another crushing knockout — becoming a two-time undisputed heavyweight champion, adding to the undisputed cruiserweight spoils he previously held.

And with his career in the sport potentially on the final turn, a host of stars have been suggested as opponents in what may come as Oleksandr Usyk’s final venture to the ring next time.

But there’s one potential fight for the Ukrainian star which may prove his biggest test to date — especially if they make a long-mooted leap in division.

Johnny Fisher names potential threat to Oleksandr Usyk’s reign

Dominating two separate divisions since his move from the amateurs, Usyk had turned in a laundry list of notable wins over the sport’s biggest stars of the modern era.

But according to London prospect, Johnny Fisher — there’s a potential threat to Usyk’s reign a division currently lower than the Ukrainian, particularly if they meet at a special weight limit.

“I think Jai Opetaia could beat him (Oleksandr Usyk),” Fisher told Seconds Out.

“At cruiserweight — if he comes up [to heavyweight]. Or, if they meet at bridgerweight.”

Furthermore, Fisher is not the only British boxing star to suggest a potential future pairing of Usyk and undefeated cruiserweight champion, Jai Opetaia.

Gunning to replicate Usyk’s prior success as undisputed cruiserweight champion, Opetaia boasts a staggering 22 knockout wins over the course of his 27-0 career.

And receiving props in his bid to emulate Usyk’s success, as well as backing to potentially hand the megastar his first pro defeat, the Australian has been sounded out as a future foe.

As mentioned, attempting to land the undisputed cruiserweight championship, Opetaia, however, has been linked with a heavyweight climb in the not too distant future.

And as far as Matchroom Boxing leader Eddie Hearn is concerned, in just a year’s time, Opetaia could position himself to take on Usyk for the undisputed heavyweight crown — particularly if he keeps winning.

“The medium focus right now for him (Opetaia) is every belt in the division,” Hearn told ESNEWS. “And the long-term focus is to fight Usyk for the unified heavyweight world championship.

“I believe he is the only fighter who can give Usyk a real fight over the next 12-18 months.”
