Devin Haney and Shakur Stevenson better be ready for Gervonta Davis ... 'cause the boxing champ tells TMZ Sports he's coming for them -- wanting fights with the stars after he gets done whooping Ryan Garcia.
"I'm pushing for it," the 27-0 lightweight says. "I'm pushing for it."
Of course, Tank has a fight already lined up that he has to take care of before he can even think about throwing hands with Haney, Stevenson and Garcia ... his next bout is just a couple weeks away -- against Hector Luis Garcia on Jan.
