The Brazilian fighter Jaqueline Amorim has been handed a six-month suspension by the UFC for violating the anti-doping policy. According to reports from the Combat Sports Anti-Doping (CSAD), traces of ostarine, a banned anabolic substance, were detected in two out-of-competition samples collected in July and August 2026. This led to a retroactive sanction starting on August 17, 2026, the date the violation was recorded.
Involuntary contamination recognized
Unlike cases of intentional doping, the tests revealed involuntary contamination with ostarine. The CSAD clarified that no performance enhancement was observed in the fighter, allowing the violation to be classified as unintentional. Jaqueline Amorim fully cooperated with the investigation, facilitating the sanction process.
Return to competition expected in February 2027
Despite the suspension, the CSAD emphasized that Jaqueline Amorim’s record remains untarnished. Her last fight, a submission win over Loma Lookboonmee at UFC Macau on May 30, 2026, will not be overturned. The Brazilian fighter will be eligible to return to the cage in February 2027, once her suspension period is complete.
A reminder of the importance of anti-doping controls
This case once again highlights the importance of strict testing in combat sports. The CSAD stressed that athletes must exercise extreme caution, even outside competition periods, to avoid accidental contamination. A lesson that applies to all fighters, whether active or in training.
