The boxing legend, 56, rejected Bare Knuckle FC’s insane offer because he’s looking to return to traditional boxing, according to Marca. Mike Tyson has turned down a huge $18 million offer to face MMA legend Wanderlei Silva in a bare knuckle fight.

Tyson is looking to return to the sport after showing off his incredible physique and blistering power in a series of training videos on social media.

And Cordeiro believes ‘Iron’ Mike still has the speed and power of a 21-year-old.

“As soon as we started training I said ‘My Lord,’” the Brazilian coach explained. “I didn’t know what to expect from a guy who hasn’t hit mitts for – I think – almost ten years.

“So, I didn’t expect to see what I saw – I saw a guy with the same speed, the same power as a guy who is 21, 22-years-old.

“And I can tell; you would have to be a good guy to spar with Mike, because if you don’t prepare, he is going to drop you for sure – 100%. The power is different level.

“I have trained a lot of heavyweights in my career, with not a lot of respect for everybody, but he is almost as powerful as Wanderlei Silva is right now.

“When you talk about power, I held his right hook and thought ‘he is going to kill somebody.’”
