Heavyweight boxing icon Mike Tyson has been offered $1 million to step into the ring with New Zealand rugby star Sonny Bill Williams.

Tyson, aged 53, went viral on social media last week after posting a video of himself working on the pads, displaying his trademark ferocious speed and power is still there.

Former champion Oscar de la Hoya to speculated that the reformed Baddest Man on the Planet could still mix it with current heavyweights.

But Tyson is considering a return to the ring for three-round charity bouts only and Australian promoter Brian Amatruda is keen to get something on Down Under.

He floated the prospect of Tyson stepping in with All Blacks centre Williams, who has won all seven of his bouts but has not boxed since 2015.

The other options Amatruda discussed were former AFL star Barry Hall and retired NRL star Paul Gallen.

“The first thing I did was contact Max Markson (celebrity agent) and ask him to offer Tyson $1 million,” Armatruda told the Daily Mail.

“He might be 53 years old but he’s still a huge name and any of those blokes – Hall, Gallen or Sonny Bill – would jump at the chance to get into the ring with him.

“I’d make it part of a card with a world title fight. It would be enormous. Not just a fight, it would be an event.

“We’d have to wait until the coronavirus shutdowns are over of course so the fight probably wouldn’t be until early next year.”

Williams’ most impressive victory to date came against former world champion Francois Botha in 2013.
