Gervonta "Tank" Davis made it known that he wants to smash on UFC fighters -- but before that, he says he's gotta remind the boxing world why he's known as the "mini Mike Tyson."
"I have to prove myself to show people that I am a champion," Davis told TMZ Sports. "I'm ready to take over the sport of boxing."
Tank admits he didn't bring his A-game in his last scrap -- the co-main event of Mayweather vs. McGregor -- even though he won by KO .
