Callum Smith may be about to split from Eddie Hearn and join a rival promoter, according to his trainer Joe Gallagher.

The WBA and Ring Magazine super-middleweight champion, widely regarded as the best in the division, claimed his crown by knocking out George Groves in the World Boxing Super Series final last September, but has fought just once since.

Smith took time out following the birth of his daughter and returned with a knockout of Hassan N’Dam on Anthony Joshua’s undercard in June.

Hearn previously stated than he was planning for the 29-year-old to headline a Liverpool show in September/October, though this is yet to materialise and now it appears we know why.

Gallagher told Sky Sports rival promoters had made contact and said: “Callum has a few lucrative offers on the table. He is considering them because they could lead to big fights. His head has been turned.

“We’re now waiting to see what Eddie can offer Callum. Callum wants big-name US-based fighters like Sergey Kovalev, Canelo, David Benavidez and Caleb Plant.”

Hearn recently signed WBO super-middleweight champion Billy Joe Saunders, but has no plans to make an in-house unification fight later this year.

He responded by saying: “We are planning Callum’s next fight for October time before a huge fight in the spring, most likely at Anfield.

“Obviously in signing Billy Joe Saunders we have the perfect opponent for a huge domestic fight.

“But Callum is also in the mix for all the big names on [US broadcaster] DAZN including Canelo Alvarez and Gennady Golovkin.”
