Published anti-doping rulings against UFC athletes from USADA and Combat Sports Anti-Doping, including the substance involved and the period of ineligibility served.
These are disciplinary findings under the UFC Anti-Doping Policy. They are distinct from the routine post-fight medical suspensions listed elsewhere in this section, which imply no wrongdoing.
This page reproduces publicly reported regulatory and medical-administrative records. Every entry names the body that issued it. Anti-doping testing entries are counts of publicly reported test sessions and are not pass/fail results — a test session is not a positive test. Records are reproduced as published and are not medical advice.
