Recent UFC signee Felipe Olivieri has been informed of a potential failed drug test by the United State Anti-Doping Agency (USADA).
The lightweight fighter from Nova Uniao fell to Tony Martin via rear-naked choke in the third-round of an undercard bout at UFC on FOX 18 this past January.
Ultimate Fighting Championship (UFC), who is an ally of USADA, published an official statement, which reads "USADA will handle the results management and appropriate adjudication of this case involving Olivieri, as it relates to the UFC Anti-Doping Policy and future UFC participation."
The test in question is not Olivieri's post-fight sample -- that one came back negative.
