Kell Brook’s promoter has flagged up the importance of the boxer’s need to be mentally resolute ahead of his first fight since being stabbed in Tenerife.
Eddie Hearn said there were no doubts about his physical condition - “he is better than ever.”
But he added: “It is a massive night for Sheffield and for Kell Brook. Everything that has gone on in his life in the last eight months... it all comes down to Saturday.
“I think it is about keeping his emotions and mental state in check ahead of a huge night.”
Brook, whose leg was injured by a machete-attacker while on holiday last year, says he is “bang on” for his first IBF welterweight defence against Romanian-born Jo Jo Dan.
He respects his opponent, who has only lost twice, both times on points. “He has never been stopped but I like to do what nobody else has done” said Brook, who is heavy favourite to triumph.
“I want to show him and everybody I am a world champion and at a different level. I want to tell everybody I am back. I am going to enjoy this.”
Some observers have criticised the quality of Dan, 33.
“He is the mandatory and, yes, in some ways, I will be glad to get mandatory over with” Brook told The Star. “I am looking forward to spending time with my family, it has been a long camp because we had to start off with my leg injury slowly. It was baby steps. Then it was full speed at it. But I am going to do the job.”
The event at the Arena promises to be a big night for Barnsley boxer and stablemate Lee Noble, who has been fighting leukaemia.
Brook, 28, who is 1/16 to win, says: “I think he has got over the cancer and it has left him. I think it has been his dream to carry a world title belt into the ring and I’d like to make it happen.”
n Brook will be ringside for Floyd Mayweather v Manny Pacquiao, hoping to stake a claim to meet the winner.
