Silva was scheduled to face Kelvin Gastelum at Shanghai’s UFC Fight Night 122 on Nov. 25 but has since been pulled from the card. The UFC is currently looking for a replacement for Gastelum.
Siva had previously tested positive for a UFC 183 fight against Nick Diaz in 2015. He was suspended for a year and fined $380,000 USD.
The UFC released a statement on its website:
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.
