The Charlo brothers appear more interested than Adrien Broner in working with British promoter Eddie Hearn.

Jermall Charlo told ESPN.com on Wednesday night that he and his twin brother, Jermell Charlo, are “definitely open to” discussing potential promotional deals with Hearn’s Matchroom Boxing USA. Jermall Charlo (27-0, 21 KOs), the WBC’s interim middleweight champion, and Jermell Charlo (30-0, 15 KOs), the WBC super welterweight champ, both work with adviser Al Haymon, but neither fighter has a contract with a promoter.

Jermall Charlo told ESPN.com that he has discussed with Haymon their plans to explore promotional deals with Hearn.

“We’re definitely open to it and to hearing what he has to say,” Jermall Charlo said. “And me and my twin brother are willing to work something out if it makes sense. Of course, I want to hear what he has to say.”

Broner went as far as to call Hearn’s three-fight, $6.75 million offer a “slave deal” when he publicly turned it down Wednesday through his Instagram account.

Jermall Charlo also told ESPN.com that representatives for Bob Arum’s Top Rank Inc. have inquired recently about signing him and his brother to promotional contracts. Arum also wants to add top fighters to showcase as part of his company’s exclusive deal with ESPN.

Hearn said when he officially announced his lucrative streaming deal with the Perform Group two weeks ago that the Charlo brothers would be two of his top targets to sign. The Houston natives have emerged over the past year as two of the more entertaining boxers in the sport.

Jermall Charlo most recently knocked out Hugo Centeno Jr. (26-2, 14 KOs, 1 NC) in the second round to win the WBC interim middleweight title April 21 at Barclays Center in Brooklyn. The former IBF junior middleweight champ also maintained his status as the WBC’s mandatory challenger for middleweight champion Gennady Golovkin (38-0-1, 34 KOs).

Jermell Charlo scored spectacular knockouts in each of his last two fights, both at Barclays Center. He knocked out Dallas’ Charles Hatley (27-2-1, 19 KOs) in the sixth round 13 months ago and stopped Erickson Lubin (19-1, 14 KOs) in the first round October 14.

Jermell Charlo is scheduled to make an optional defense of his 154-pound championship June 9 against Austin Trout (31-4, 17 KOs), of Las Cruces, New Mexico. Showtime will televise the Charlo-Trout bout as part of a doubleheader from Staples Center in Los Angeles.
