French footballer and Real Madrid star Karim Benzema replied with three fire emojis.
Iron Mike's son Amir said "Beast Mode", while the man who is set to play Tyson in the movie on his life Hollywood star Jamie Foxx commented simply "Boss".
Ring Magazine journalist Ryan Songalia even tweeted: "It's always been about the "return" of Mike Tyson (featuring guest star Roy Jones Jr.), I think Iron Mike would do big numbers hitting the punch mitts on PPV if Roy pulled out".
It comes as Jones Jr threatens to pull out of the bout with Tyson telling The Daily Mail he has a few issues with the date change, wanting to be compensated for the date move.
Originally the pair were meant to fight on September 13 after reports suggested that Tyson wanted the change to fans to return to the stands.
"We're trying to figure something out. My lawyers (are) talking with their lawyers, trying to figure out ways to make it a better situation so that I can compensated for it, that is more beneficial for me to do," Jones Jr said. "If they don't make it make sense, (the fight) would be off.
"Why would I change the date and mess up the rest of my year when I agreed to September 12? They said they wanted to get a crowd. If you want to get a crowd, that's a different type of money. If you want a big event, that's a different type of money.
"You think I'm going to say, OK, let's look at my money, but I'm not getting no better per cent. How dumb is that to me? So let's see what happens."
While Jones Jr has been flying relatively under the radar, Tyson has once again posted a scary video with TMZ Sports picking up the footage.
While there is still more than three month before the boxing legends go toe to toe, Tyson has already thrown down the gauntlet.
