Derek Chisora has been placed on a six-week sex ban to help him give Oleksandr Usyk a Halloween fright tonight.
The British heavyweight takes on the former cruiserweight king at Wembley Arena.
Chisora, 36, is a huge underdog against the Ukrainian ace, who is gunning for world titles in the sport's top division.
But his manager and motivator David Haye has been trying everything to give his man a chance.
And that includes a bizarre plan Haye would abide by in his career that has left Chisora pacing around his room like a 'caged animal' in the Covid-secure 'bubble' this week.
“About 12 weeks ago, I said to him: if you want to win this fight you need to do something you’ve never done before,” said former two-weight world champion Haye.
“You need to eat the right food, you need to get X amount of hours of sleep, you need to do all these training sessions, you need to have one day off a week.
“When it gets to six weeks, you’re not going to be allowed to e******** six weeks before a fight.
“He said, 'Ah, I don’t know about that'.
“I told him I need you in the ring knowing that you’ve done stuff that you’ve never done before, you’ve sacrificed.
“Before the fight you need to be fully loaded in every department. The engine tank, your nut s***, everything needs to be full and ready to go.
“I said, 'When is a lion most dangerous?' When it hasn’t mated and it’s hungry.
“And when I see him pacing up and down, I don’t know if he’s thinking about fighting or f****** or what. I think I’ve figured it out – that’s why he’s walking up and down.”
So while most athletes use ice baths to help recover from gruelling sessions in the gym, Chisora needs them for another reason.
Chisora said: “Celibate is alright. I feel sorry the priests. That is why I take ice baths.”
Chisora may be pent up but just hours away from the bout he was still acting like a doting dad when his daughter Angelina was brought up in conversation.
His seven-year-old girl has never been interested in his boxing career before but she has watched a Sky documentary on repeat all this week.
“She has watched it 20 times since I left the house,” said Chisora.
“She wakes up and watches it. She is seeing things she has never seen before.
“Her eyes are opened, she has realised who her dad is.
“She has seen me throw the table [before Dillian Whyte fight] and she is like 'Wow' and then her mother is like, 'You've got a big fan at home now because she hasn't stopped watching it'.
“Her mother tells her 'I don't want to watch this anymore' and she says back 'Don't be jealous because you're not on TV'. She is probably going to watch the fight.”
So when he is deep in the trenches with one of the best pound-for-pound fighters on the planet and up against the odds will knowing his daughter has tuned in help him?
“I don't need help from my kids,” he added.
“It's going to get tough for him and me. It's not one-way traffic this.”
