American boxing legend, Mike Tyson has shown off his impressive physique ahead of his comeback fight with Roy Jones Jr on November 28.

The 54-year-old took to Instagram to share a series of new photos, revealing the results of his rigorous training regime just 11 days before the highly-anticipated exhibition fight that is due to take place at the Staples Center in Los Angeles.

Speaking of his transformation earlier this summer, Tyson told TMZ Sports: ‘At one time I was just 90lbs overweight. I was doing cocaine, I was drinking and I said, “Allah if he can stop me from being this way, I’ll change my whole life”.’

‘And eventually, I got married, my life started to change, and I started working out.

‘My brother in law said, “hey listen. I know you don’t want to fight, but would you fight Bob Sapp?

‘Somebody wants to offer you a lot of money to fight him. I said, “get out of here, I told you I don’t want to fight anymore.”

‘And then I thought about it in my mind and went “ding” – I said I would fight [Sapp under the Marquess of Queensberry rules] and for some reason, it went from Bob Sapp to somebody else, and this guy, and the next thing you know, I’m fighting Roy Jones Jr.

‘I don’t know how this happened. I’m just very grateful that I’m not living the life that I was living before. Allah has blessed for me to be able to do this.’
