Kell Brook's cut back to the welterweight limit after last fighting 13lbs heavier could be a stumbling block, says Johnny Nelson.
Going in there [with Gennady Golovkin] you thought Kell was a solid, chunky light-middleweight. Now he's going back down to welterweight and that's an issue.
He's not a happy bunny when he has to get down to welterweight. Each time he does it, it gets harder and harder.
The weight is the issue, it's my worry. Kell is a big, strong unit so he's having to squeeze down to welterweight. You have to diet, you need serious discipline, you need to be on point with it. He's not a happy bunny when he has to get down to welterweight. Each time he does it, it gets harder and harder.
Spence Jr is hoping this is the straw that breaks the camel's back. Spence Jr's team are working on body shots because they know that, when you drag your weight down, you are weak around the mid-section. Your energy levels are going to deplete in rounds six and seven.
He will make the weight regardless, but it depends how he makes it. Will he be strong? Spence Jr's team are expecting this fight to hinge on how Kell makes the weight, and what he looks like.
The American journalists have got it wrong before - Gerald McClellan against Nigel Benn, Lucien Bute against Carl Froch, Jeff Lacy against Joe Calzaghe.
Most fighters from a loss are heartbroken but Kell was lifted. He was gutted that he didn't win [against Golovkin], but he went out on his shield. It's given him confidence because he now knows what he's capable of doing.
