Felipe Oliveiri is the latest UFC fighter to come under scrutiny with the U.S. Anti-Doping Agency, as the Brazilian’s test came back positive for a banned substance.

Oliveiri made his debut this past January against Tony Martin, suffering a submission loss. The 29-year-old is 14-4 with one no-contest in his career, having fought for Shooto Brazil and Pancrase while training at the Nova Uniao gym in Brazil.

The complete statement from the UFC regarding the matter can be found below:

The UFC organization was notified today that the U.S. Anti-Doping Agency (USADA) has informed Felipe Olivieri of a potential Anti-Doping Policy violation stemming from an out-of-competition sample collection. Although the sample collected from Olivieri following his bout at UFC Fight Night: Johnson vs. Bader on January 30, 2016, was reported as negative for prohibited substances, a sample collected from him in Brazil earlier that month, and analyzed at the WADA accredited laboratory in Rio de Janeiro, was recently reported to USADA as containing a prohibited substance.

USADA, the independent administrator of the UFC Anti-Doping Policy, 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. Because Olivieri participated in a bout sanctioned by the New Jersey State Athletic Control Board after the sample in question was collected, USADA will work to ensure that the Board has the necessary information to determine the appropriate course of action under the Board’s rules.
