He may not be interested in fighting Sonny Bill Williams but American boxing legend Mike Tyson has hinted at a return to the sport.
Tyson first sparked chatter about a potential comeback after wowing fans in a ferocious sparring session in a video that went viral.
The 53-year-old, who hasn't entered the ring as a professional in 15 years, has posted another impressive sparring video on social media before saying "I'm back".
Tyson has yet to announce any plans to return to fight again, though he did suggest in a previous Instagram post he might make himself available for 3 or 4-round exhibitions if the price was right.
