Heavyweight legend Mike Tyson could soon be returning to the boxing ring to fight former New Zealand rugby union star Sonny Bill Williams.

The boxing icon has revealed his ambitions to return to the ring to compete in charity fights, and has recently been training to get into shape ahead of a potential comeback. 

And after Tyson wowed fans by engaging in a ferocious sparring session in a Youtube video, Melbourne boxing promoter Brian Amatruda immediately got on the phone to arrange a charity bout for the former world heavyweight champion. 

The 53-year-old could either face Williams, former rugby league star Paul Gallen or retired Australian rules footballer Barry Hall. 

Amatruda is confident he could arrange a charity bout for Tyson in Melbourne that would fill any of the city's biggest arenas.

The promoter said: 'I'd hold it at Melbourne Arena where we'd get over 10,000 or even Princes Park where they got 30,000 for Jeff Fenech versus Azumah Nelson.
