Eddie Hearn told Ringside that he and his team need to get Kell Brook's preparations right if the Sheffield star is to fulfil his true potential.

The unbeaten welterweight needed a majority decision to get past durable journeyman Carson Jones in his home town on Saturday night after visibly tiring as the 12 rounds wore on.

And both Brook and his promoter, Hearn, hinted afterwards at a less than perfect training camp and problems making the weight.

Hearn said: "I alluded to the fact that going into the fight the preparations were not brilliant and that if it went into the late rounds we could have a problem.

The first six rounds were plain sailing and Kell boxed superbly, but then the tide turned.

"There are ways to prepare and ways not to prepare; there are different levels.

"You can prepare for a British title level and you can prepare for world title level. I believe you have to prepare for the fighter you want to be.

"We want Kell Brook to be a pound-for-pound great and at the moment he is not preparing like a pound-for-pound great.

"As you step up in level, you will be found out if you don't prepare properly, but he will learn a lot from this fight though."

Down in the dumps

"Kell is very down in the dumps and feels like this was a loss," added Hearn. "He is an extraordinary talent but we need to get him fighting over 12 rounds ferociously and at a great pace.

"If we can do that then he will be one the best the country has ever had but we have a lot of work to do, which in a way quite pleases me.

"Everyone wants to rush him on, but we will do what is right for Kell Brook and takes the right fights ant the right time.

"What we did see was different attributes that we did not know about which were heart, chin and pure guts. If we can marry that into his natural talents, then we have got something very special."

Hearn's fellow Ringside guest, Joe Calzaghe, also thinks that Brook would have learnt a lot from his fight with Jones, and believes the 26-year-old has what it takes to get to the top of the boxing world.

"For the first six rounds he boxed well but then he ran out of steam," said Calzaghe. "It was all about heart in the the second half of the fight and that will hold Kell in good stead.

"He had 12 hard rounds and now realises what you need at the top level and what he needs to do to box 12 rounds and not six rounds.

"I think he can go all the way but he needs to improve as he has not got the fitness levels to go 12 rounds, whereas the top fighters do."
