- Sheffield fighter won world title against Shawn Porter in 2014
- “I’ve finished now with all my faculties intact,” says Brook
Kell Brook says he is retiring from boxing after his grudge-match win over Amir Khan brought him peace.
The Sheffield fighter, now 36, held the IBF welterweight title between 2014 and 2017, but will perhaps best be remembered by British fans for finally facing, and beating, his rival Khan in February this year.
