KELL BROOK had some of the most intense but rewarding nights in British boxing history.
Brook will fight Amir Khan this Saturday, a fight that will be a lasting one.
Kell Brook, before his fight with Terence Crawford
The Sheffield switch-hitter, however, has been a popular figure in the UK and USA.
SunSport details Brook's difficult career and the transformation that his body has undergone.
Welterweight
Brook was a debutant in the 147lb division (10st 7lb), and he worked tirelessly to climb the ranks.
He was eventually able to get into an IBF mandatory role and stunned Shawn Porter in California in 2014 to win the belt.
Brook defended his title three times before moving up to middleweight. However, Brook lost the belt to Errol Spence Jr.
In 2020, the Brit returned to welterweight but was defeated by Terence Crawford in his final fight.
Light-middleweight
Brook lost his welterweight title in 2017 to Spence. He then moved up to 154lb (11st), to try and become a two-weight champion.
In his new division, he beat Mark DeLuca, Michael Zerafa, and Sergey Rabchenko.
Brook looked like he was on his way to a title shot, and he seemed to be getting healthier in weight.
However, he accepted a deal to return to Crawford and it ended his light-middle success.
Middleweight
Brook stunned the boxing world in 2016 by jumping two weight divisions, from welterweight at 160lb to middleweight at 160lb (11st 6lb).
Brook was surprised to be offered the chance to fight Gennady Gorlovkin, a Kazakh danger-man Gennady Eubank Jr.
He started the fight well, winning the first round. But GGG's size, power, and strength proved too decisive to stop him in round 5.
Brook dropped back to welterweight one year later in order to face Spence. He looked gaunt.
Amir Khan catchweight
They finally reached an agreement to fight as their careers were in the final stages.
Brook was not able to reach the welterweight limit, and this cost him dearly.
Khan suggested a catchweight for Khan of 149lb (11st 6lb), which is just 2lb more than the welterweight.
A contract penalty of PS100,000.000 will be applied for each lb fighter who is unable to lose weight.
