RIO DE JANEIRO -- UFC featherweight champion Jose Aldo was randomly drug tested last Thursday in Brazil, but the urine sample was discarded after local authorities found out that Drug Free Sport’s Ben Mosier didn’t have a proper visa to work in Brazil. Aldo was tested again on Friday by Brazilian MMA Athletic Commission (CABMMA), but UFC 189 opponent Conor McGregor was suspicious about it.
McGregor called Aldo a "little weasel", and also targeted his coach Andre Pederneiras after the whole thing was over, and the Nova Uniao stars decided to respond.
