Kyrie Irving Better Watch His Back in Cleveland, Says Bone Thugs Rapper

Kyrie Irving could have some serious issues when he returns to Ohio ... so says Bone Thugs-N-Harmony's Wish Bone, who thinks Irving's DEAD WRONG to say Cleveland's not a sports city.

ICYMI -- K.I. struck a chord with Cavs fans for saying he was finally playing in a "a real, live sports city" after his trade to Boston ... which was taken as throwing shade at his old city.

Wish Bone -- a huge Cavs supporter from Cleveland -- says Irving's no longer welcome in northeast Ohio ... and hints he'll have to keep his head on a swivel if he tries to walk the streets of Cleveland again.
