Following his TKO victory over Vitor Belfort at UFC Fight Night 106 Kelvin Gastelum tested positive for Carboxy-Tetrahydrocannabonol above the in competition threshold allowed by WADA standards. USADA provisionally suspended Gastelum pending results management.
The Brazilian MMA Sports Court (STJDMMA), who also enjoy jurisdiction over the matter, sought to punish Gastelum and reached a plea with the fighter. As first reported by Raphael Marinho of Brazil’s Combate, a plea was reached resulting in a 90 day suspension retroactive to March 11, a 20% fine of his purse and the victory is overturned to a no contest.
USADA’s result management process remains underway.
