Kelvin Gastelum has been pulled from a scheduled fight against Anderson Silva at UFC 212 on June 3 due to potentially failing a drug test.
Per an official statement from UFC, Gastelum failed a United States Anti-Doping Agency-administered drug test for having traces of marijuana in his sample. The company placed him on a provisional suspension.
Gastelum's potential violation came from the sample collected after his win over Vitor Belfort at UFC Fight Night on March 11.
UFC also said it is searching for a replacement to take Gastelum's spot on the card against Silva, though no potential challengers were named.
The 25-year-old Gastelum has been rising up the middleweight standings, climbing to No. 8 in UFC's official rankings, with consecutive wins over Belfort, Tim Kennedy and Johny Hendricks. He owns a 14-2 career record in mixed martial arts, including nine wins in 11 UFC fights.
