Kell Brook will face Pound for Pound star Terence Crawford for the WBO welterweight title on November 14, but it will be a new-look Brook who is set to be without his long-term promoter and trainer.
Eddie Hearn and Dominic Ingle will not be present for the fight, which is expected to take place in Las Vegas.
It is believed Brook is looking to cash out with the exclusion of Hearn whilst Ingle was unprepared to travel to Spain in order to help Brook train for one of the toughest fights of his career.
Ingle told IFL TV: "I'm the trainer. I'm not going to have anyone tell me how they want they want their camp running.
"Some fighters might do that but it's never been that way with me. I stipulate how the camp is and what we're going to do. If he's not happy with that, then he can do it somewhere else.
"Realistically, Kell doesn't need to be anywhere else but Sheffield.
"Why would you take the risk? During these times, why would you take the risk to go abroad? He's in a big fight with Crawford. Whether it's an exercise in saving money or whatever it is, that's down to him.
"I don't know who is training him. We haven't fallen out. We're never going to fall out.
"He does his own thing. Like I say, he's 34, he has three kids, he's made his money. We've had a good run."
TV rights to Crawford-Brook up in air
Brook's fight will feature on ESPN in the United States but in the UK, it is unclear with Sky Sports unwilling to pick up the fight.
It leaves BT Sport, FITE TV, ITV and BoxNation as the front-runners to host the fight, although there remains a chance the bout could miss out on a broadcaster in Britain.
Speaking about Brook's decision to dump Hearn, Ingle added: "Eddie has promoted him all this time. He's not doing this fight with Eddie. He's not doing this fight with his promoter, and he's not doing this fight with his trainer.
"That's fair enough. That's not an issue. Eddie will still be promoting other fighters and I'll still be training other fighters. We've all got jobs to do.
"You make your choices in what's good for you. I can't take the risk. What's going on in this day and age with Covid, I can't get caught up in all that.
"I've to keep away from it. For me, it wouldn't be a wise choice. He's got to travel to America, fair enough. I don't want to get caught in quarantine somewhere. That's how it is."
