Footage shared by Shannon Briggs on Instagram shows Tyson flexing his muscles in a rage, proving his hard work in the gym is clearly paying off.
Briggs captioned the video with "Look at em y'all!!! ABSOLUTE POWER!"
Comments on social media attested to Briggs' claim about the former world heavyweight champion, with one saying "he's done hibernating. Looks like old Mike is back. Be afraid."
Another said "man I think Roy is in trouble! Roy's the man, just as Tyson is, but I just can't see Roy pulling this one off."
"Mike Tyson is winning this in the first round," another affirmed.
Jones Jr. is not the only one who is worried about safety in the fight. The WBC have altered rules, changing the structure to eight rounds of two minutes.
