Barry Hearn, the founder of Matchroom Sport, took a sharp dig at unbeaten heavyweight contender Tyson Fury, who returns on June 15th against Tom Schwarz at the MGM Grand in Las Vegas.

The elder Hearn was in charge of a press conference on Monday to announce a heavyweight contest between top contenders Dillian Whyte and Oscar Rivas.

Rivas was in the running to face Fury on the June date, but the Gypsy King and his handlers rejected the fight in favor of Schwarz.

Hearn took the opportunity during the presser to take a stab at Fury's fight - stating that Schwarz was a very low level opponent.

While Schwarz has a high ranking under the WBO, he's never really faced top opposition or beaten highly ranked opponents. Fury is a tremendous step up in class.

“Tyson Fury is the best gypsy boxer in the world, isn’t he? The king of the gypsies who’ll fight any man whatsoever? Ah, his next opponent’s ranked number 93 with BoxRec," Barry Hearn stated. "Congratulations, make of it what you want, but let’s have no bulls*t, shall we?"

Rivas was on the verge of signing a deal with ESPN and Top Rank, when the offer to face Whyte came down.

Rivas' promoter, Yvon Michel of GYM, explained that Fury and his handlers claimed that they needed an opponent who was very tall, in order to prepare for future opponent with height. One would assume they selected Schwarz to prepare for a rematch with Deontay Wilder, but Fury's co-promoter, Bob Arum of Top Rank, has already stated that a rematch would not happen until next year at the earliest.

"Right after, especially when ESPN signed Tyson Fury , we were told he might have had the task to be the opponent of Tyson Fury. Then we learned that Fury didn't want to fight Oscar because of styles. He said it was not good for him because he wanted to get ready for a taller opponent," Michel told The Mirror.

"We were working on having another stay-busy fight, and we were offered Michael Hunter, Andy Ruiz Jr, Joe Parker, and we said yes to all offers we got. Finally, we learnt they were turned down by the opponents and we got the call (to face Whyte)."
