Eddie Hearn, promoter for WBA super middleweight champion Callum Smith, has made a request to the World Boxing Council - asking the sanctioning body to order a mandatory fight with WBC world champion David Benavidez.
Smith, who at one point was the mandatory challenger, decided to take part in World Boxing Super Series tournament. He won the entire tournament with a knockout of George Groves in the series final in 2018.
As part of that tournament, he captured the WBC's Diamond title at 160-pounds - which gives him a crack at the title.
Smith is back in the ring on November 23rd, when he faces mandatory challenger John Ryder.
Benavidez reclaimed the WBC world title last weekend, when he stopped Anthony Dirrell at the Staples Center in Los Angeles.
Another potential fight for Smith is a unification with WBO world champion Billy Joe Saunders, who is also promoted by Hearn's Matchroom Sport.
"Callum Smith, in 2020, is looking at all the career-defining fights," said Hearn to Sky Sports. "Obviously we've got Billy Joe Saunders now with Matchroom on Sky and that's a unification fight that could be made quite easily.
"You've got David Benavidez, which is a fight we've written to the WBC, and requested them to order now. So 2020 is going to be great, but as we know in boxing anything can happen and [there is] full focus on him for the 23rd [of November], but certainly 2020, leads to massive fights for Callum Smith."
Smith (26-0, 19 KOS) was in action earlier this year, when he demolished former champion Hassan N'Dam in three rounds on the undercard to Anthony Joshua-Andy Ruiz, which took place on June 1 at Madison Square Garden in New York City.
