The Mexican fighter recently became the undisputed super-middleweight champion after beating Caleb Plant and will now fight world champion Ilunga Makabu in the higher weight division, much to Hearn's delight.
The promoter - who has previously worked with Canelo - told IFL TV: "I think with Canelo and Eddie Reynoso, they want challenges. They want to dare to be great which is tremendous for the sport. The Makabu fight is a cruiserweight fight that would give him another world championship victory, would get a lot of people talking as it did last night, and I think it’s a good option for him."
Hearn believes that the clash is a "dangerous" challenge for Canelo to take on.
He said: "I think it’s a dangerous fight. I was speaking to Tony Bellew – who could be looking real good in a few months if this happens – and he said that Makabu is a huge puncher, huge puncher, and very strong."
Hearn even claimed that Canelo could compete in the heavyweight division.
The promoter explained: "Listen, he could move up and fight at heavyweight. I mean, Usyk’s not a massive heavyweight, Trevor Bryant’s a world champion as well. Can he compete against those guys? Cruiserweight first, maybe. But I like the fight against Makabu. I think it’s a dangerous fight, I think it’s an exciting fight and as I said, Saul and Eddy are interested in making history. They’re not interested in having normal, boring fights. Every fight has to mean something."
