Kelvin Gastelum will no longer face Anderson Silva at UFC 212 after he was flagged for a potential doping violation.
Gastelum was tested on the night of his last fight against Vitor Belfort last month. The sample by the United States Anti-Doping Agency (USADA) showed traces of marijuana – a substance only banned above a certain quantity for UFC athletes.

The USADA will now handle the adjudication process over UFC’s anti-doping policy, while the Brazilian MMA Athletic Commission will also be made aware of the violation.
Gastelum has been provisionally suspended as a result of the positive drugs test, as he goes through the full disciplinary process.
But with the American due to face Silva, in Brazil, on June 3, the UFC has pulled him from the card.
It is hoped that the veteran Silva will still be able to compete in his homeland, if a new opponent can be found.
