- Kell Brook v Carson Jones
Hearn: Jones battle a reality check for Brook
Eddie Hearn has told Kell Brook he must knuckle down if he wants to realise his dreams of becoming a world champion.
Brook's unbeaten record is still intact but he was given a huge scare by Carson Jones in an enthralling battle at the Motorpoint Arena in Sheffield on Saturday night.
Brook faded alarmingly in the second half of the fight but clung on to claim a majority decision to move closer to a world title shot.
While Brook concedes he needs to improve his stamina, promoter Hearn insists the 26-year-old must not cut corners in training if he wants to challenge the world's best.
"I'm happy it was tough, in a way, because in my mind I still know we've got to change a lot of things - but now he knows it," he said. "He likes his food - don't we all. But you know how tough it is making weight when you're big at the weight.
"I don't want people to think that he's just a slob. He trains very hard, he lives the life. But you live the life of perhaps a British champion. I want him to live the life of a pound-for-pound champion. I want him to do everything immaculately."
Hector Saldivia is expected to be Brook's next challenge, with victory making him the mandatory challenger for a shot at IBF welterweight title holder Randall Bailey, who faces Devon Alexander on September 8.
Hearn added: "If he [Brook] improves his preparation, fights Saldivia and looks incredible, then we're going to just dive in for a world title. We'll go mad for it."
