The United States Anti-Doping Agency (USADA) and UFC announced the rescheduling of bantamweight Ning Guangyou’s (6-3-1) bout with Marlon Vera (11-3-1) from UFC 202 to Vancouver’s UFC on FOX 21, due to a “no-fault” exception.

The announcement follows an investigation into Guangyou’s out-of-competition positive test for the substance Clenbuterol. It concluded the trace amounts found  were likely the cause of contaminated meat consumed in China. Therefore, no penalty was imposed, prompting the UFC’s decision to postpone the bout a week.

The UFC released the following statement on its website.

The UFC organization was notified today that the U.S. Anti-Doping Agency (USADA), the independent administrator of the UFC Anti-Doping Policy, has completed an investigation into the circumstances of a positive test for Ning Guangyou, resulting in a no-fault sanction with no period of ineligibility. 

In late July, UFC was made aware of USADA’s investigation into the source of the prohibited substance clenbuterol in an out of competition sample collected from Ning Guangyou. Given it was initially unclear as to the timing of the resolution of the investigation, UFC made the decision to move Guangyou’s scheduled bout against Marlon Vera on August 20, 2016 at UFC 202 to UFC Fight Night: Maia vs. Condit in Vancouver, BC on August 27, 2016.

 Future Clenbuterol incidents will be dealt with on a case-by-case basis, according to USADA.
