3:12 PM PT -- Jon Jones got wind of Fury's rant ... and while he was super complimentary of the boxing champ, he made it clear the Gypsy King stands no chance in the Octagon.
"Hey Tyson, it seems like Joe may have struck a nerve," Jones said on Twitter. "I’ll admit there’s no one touching you in that ring right now, but let’s not let that confuse you with what would happen if you stepped foot in my cage."
The most interesting part -- Jones says if Tyson wants to mess around and find out -- all he has to do is hit up UFC honcho Dana White.
