When it rains, it pours for the UFC.

For what would be the second drug test failure since 2015, Anderson Silva has been flagged by USADA for a potential violation of the UFC’s anti-doping policy.

Silva’s potential failure stems from an out-of-competition test collected on October 26th and with the former middleweight champion being flagged, ‘The Spider’ has been removed from his upcoming main event against Kelvin Gastelum later this month.

The UFC released the following statement concerning Silva’s potential violation:

The UFC organization was notified today that the U.S. Anti-Doping Agency (USADA) has informed Anderson Silva of a potential Anti-Doping Policy violation stemming from an out-of-competition sample collected on October 26, 2017. As a result, Silva has been provisionally suspended by USADA. Due to the proximity of Silva’s upcoming scheduled bout at UFC Fight Night, Shanghai, China on November 25, 2017 against Kelvin Gastelum, Silva has been removed from the card and UFC is currently seeking a replacement. USADA, the independent administrator of the UFC Anti-Doping Policy, will handle the results management and appropriate adjudication of this case involving Silva. Under the UFC Anti-Doping Policy, there is a full and fair legal process that is afforded to all athletes before any sanctions are imposed. Additional information will be provided at the appropriate time as the process moves forward.

Silva was suspended for one year in 2015 and also received a $380,000 fine after a failed drug test from his UFC 183 clash with Nick Diaz.
