Mike Tyson may be coming out of retirement for a hefty paycheck.
A trilogy exhibition fight with old foe Evander Holyfield has been widely mooted, with 57-year-old Holyfield also getting back in shape.
The American fighter, who beat Tyson twice during the 1990s, has even enlisted the help of former heavyweight champion Wladimir Klitschko to get him ready for his comeback.
But it appears Iron Mike will have not shortage of offers as he gears up for making his return to the ring 15 years after his last professional bout.
Rumours of a possible MMA fight ramped up this weekend, as Tyson was pictured training with UFC bantamweight champion Henry Cejudo and former UFC light-heavyweight champion Vitor Belfort.
And, according to MMA Fighting, the BKFC are currently devising a contract that will exceed €20million to tempt Tyson into bare knuckle fighting.
BKFC are already said to have offered Tyson $20m to fight in their competition, which he rejected.
But the company’s president David Feldman has not given up and will return with an improved offer for the boxing legend next week.
UFC Hall of Famer Tito Ortiz, 45, has been sounded out as a potential opponent for Tyson, with claims a member of Tyson’s camp had asked the MMA fighter about a possible match.
But Feldman has poured cold water on those claims, saying 43-year-old Brazilian Wanderlei Silva, former UFC fighter and PRIDE champion in Japan, is a more desirable opponent.
Tyson began his career in 1985 and ended it in 2005 with a record of 50 wins, six losses and two no contests. Forty-four of his wins came by knockout.
The boxing legend hasn't fought in a match since then. He first noted his desire to compete again in a potential charity match during a conversation with rapper T.I. on Instagram Live earlier this month.
"I've been working out, I've been trying to get in the ring. I think I'm going to box some exhibitions and get in shape," Tyson told T.I., according to Yahoo Sports. "I want to go to the gym and get in shape to be able to box three- or four-round exhibitions for some charities and stuff."
He has kept up on his training, sharing videos of his workouts on social media.
"Anything is possible when you are smart about it," Tyson wrote in the caption of a video on Instagram on May 11. "Train Smart. Recover Smarter." "I'm back," he said.
