Footage of former heavyweight champion Mike Tyson training went viral in the past week as the 53-year-old showed he still has some fight left in him -- albeit in a controlled setting. But it seems that the footage has caught the attention of the right people as Melbourne boxing promoter Brian Amatruda reportedly offered Iron Mike a million dollars to do a charity bout.

"The first thing I did was contact (celebrity agent) Max Markson and ask him to offer Tyson $1 million,' he told the Daily Mail Online. 'Max brought him to Australia in 2012. He gets on well with him and his wife but the main thing is that he got him a visa to get into the country back then and that's the key.

"We'd have to wait until the coronavirus shutdowns are over of course so the fight probably wouldn't be until early next year - as long as we can get the visa. They gave him one in 2012 and he was fine, he's a quiet family man now. He didn't cause any trouble then, so why shouldn't they let him back in?"

The fighters rumored to potentially take on Tyson are well known in Australia, but not inside the boxing ring. They include former Australian rules football star Barry Hall, retired rugby star Paul Gallen, and Sonny Bill Williams, a former member of the New Zealand national rugby team.

Back in late April, Tyson told rapper T.I. that he was getting back into fighting shape to participate in some charity matches, so the chances that this piques the retired boxer's interest aren't bad. Tyson's trainer even said that Iron Mike still has the power and speed of a 21-year-old. Needless to say, no matter who the 53-year-old ends up fighting, Tyson seems like the safer bet.
