Mike Tyson is ready to turn down a second offer of £16 million to take part in a bare-knuckle boxing fight.
The former heavyweight world champion is expected to make an announcement this week about his return to the ring.
But any comeback fight is expected to be an exhibition bout, despite the riches on offer from promotional outfit BKFC.
President David Feldman admitted Tyson rejected their first offer out of hand but that he has not given up hope.
“First, I want to see if we can make the Mike thing happen, period, and then we’ll start talking opponents,” he said.
“We’re not successful yet in making that Mike thing happen, but I don’t think the door’s shut.
“He did say no immediately. But I think there’s room there.”
Fellow former heavyweight world champion Shannon Briggs, who signed with BKFC earlier this year, has been mooted as a potential opponent for Tyson.
Former star Wanderlei Silva has also been mentioned, and Feldman added: “I think a Wanderlei Silva, someone of that nature. No matter how old Silva gets, he’s dangerous, and I think that would be an intriguing matchup. Something like that, but I don’t actually have anything in mind right now.”
But Tyson’s new coach Rafael Cordeiro dismissed the idea of the 53-year-old fighting without gloves.
“I didn’t get any calls from Wand or Tyson, but as far as I know that fight wont happen,” he said. “Tyson is training to make a boxing fight – with gloves. It is hard to comment about rumours.”
Tyson’s most-likely opponent had been Evander Holyfield who has also returned to training.
The former rivals met twice in their prime with Holyfield winning both fights, first by stoppage and then when Tyson bit part of his ear off in the rematch.
But when asked if Holyfield would be his opponent, Tyson said: “Na, na we got many guys. Listen we’ve got so many guys that want to do this, man.
“We’re in calls, we’re doing business with guys right now. You’re not going to believe the names when the names come out. Some time this week we’ll have the contract done.
“And whatever money we get, it’s going to somebody else. I’m not going to make any money – probably the company, my wife because she’s partners with me, she’ll make some probably. But my money is going [to charity].”
