Cocaine’s a helluva drug … and it will probably cost boxer Tyson Fury his championship belts.
The boxer — who just pulled out of his Oct. 29th rematch with Wladimir Klitschko — has tested positive for coke … multiple sources tell ESPN.
Fury’s people had said he pulled out because he was “medically unfit” — but now we know the boxer had failed a Sept. 22nd urine test.
Fury — the current WBO, WBA and IBO heavyweight champ — will likely be stripped of his belts and faces further punishment.
