Brook has a vision to banish all the doubts

Kell BrooK is fighting to save his career while protecting his eyes from further serious damage as he makes his overdue move up to superwelterweight tonight. That amounts to a doubly daunting task for Sheffield’s Special K as he returns to the ring after two tough defeats and the loss of his world welterweight title. Sergey rabchenko has fallen just short of world championship level but he is a heavy enough puncher and sufficiently gritty competitor to exploit any physical or psychological weakness in Brook as they collide at the Sheffield Arena. Brook, 31, has chosen a tough opponent in a bid to prove he is ready to return to the top flight against Amir Khan or one of the two best of the current crop of champions, erislandy lara and Jermell Charlo. Brook admits the public ‘have doubts’ about him following his ill-fated venture against world middleweight Ko king Gennady Golovkin and the surrender of his welterweight belt to the brilliant errol Spence Jr. He suffered successive fracturing of the sockets of the right eye by Golovkin then the left by Spence. Blurred vision has been corrected by implanting metal plates in the bone surrounding both eyes. He reports: ‘I haven’t felt any problem during heavy sparring.’ But if rabchenko lands on either of those areas, it could arouse worries about his future sight. later, Deontay Wilder hopes to win well and make it difficult for Anthony Joshua to delay a world heavyweight unification battle. WBC champion Wilder takes on luis ortiz, four weeks before Joshua goes to Cardiff to try to add Joseph Parker’s WBo belt to his WBA, IBF and IBo collection. Wilder said: ‘AJ and eddie Hearn are worried because they know I have the big punch and the style to beat him.’
