The Daniel Jacobs vs. Sergiy Derevyanchenko fight is headed to a purse bid on July 5, which might lead to the event's undoing.

Lou DiBella, Derevyanchenko's promoter, would like to avoid limiting the fight to HBO, which has Jacobs under contract, and letting the market decide who gets to stage the fight.

Jacobs (34-2 29 KOs) would be unable to participate in a fight for the vacant IBF middleweight title — recently stripped from Gennady "GGG" Golovkin — if it lands anywhere else.

ESPN has emerged as the next-likeliest location Top Rank would be willing to put the fight there, according to RingTV. Jacobs' promoter Eddie Hearn has said that if Derevyanchenko (12-0, 10 KOs) doesn't fight Jacobs and faces off against another opponent, such as Demetrius Andrade, his wallet will take a hit.

“His next fight will be on HBO. Will they come up with enough money? If we don’t reach a deal, Derevyanchenko will fight Demetrius Andrade for half of what we might be able to get him to fight Daniel Jacobs," Hearn told RingTV.com.

“If [DiBella] doesn’t make the fight, he'll end up fighting Andrade for peanuts.”

Jacobs would have the option to go through the WBA for a middleweight title where he'd face Golovkin, who beat Maciej Sulecki by unanimous decision last April.

He'd have to wait for the winner of Golovkin vs. Saul "Canelo" Alvarez II, though, which might be smarter considering Derevyanchenko's recent form.
