UFC strawweight Jaqueline Amorim suspended six months after positive ostarine test

UFC strawweight Jaqueline Amorim has been suspended six months by Combat Sports Anti-Doping (CSAD) after testing positive for ostarine, a prohibited anabolic agent, according to an official statement published on UFC.com.

CSAD collected two out-of-competition samples from Amorim, on July 29 and August 17, 2026, both in Fort Lauderdale, Florida. Both positive findings were combined into a single violation. The suspension is backdated to the August 17 notification date and runs through February 17, 2027, when Amorim becomes eligible to compete again, Yahoo Sports reported, confirming the timeline in the official statement.

According to the UFC.com statement, CSAD determined the positive tests reflected low-level contamination rather than deliberate doping. The agency cited Amorim's prior clean testing history, the low concentrations detected in both samples, her use of dietary supplements that had not been third-party tested or certified, and the documented prevalence of ostarine contamination in supplements generally. CSAD also said the exposure did not give Amorim a meaningful competitive advantage.

Amorim, a Brazilian strawweight and Checkmat-trained Brazilian jiu-jitsu black belt, last fought on May 30, 2026, at UFC Macau, winning by a first-round armbar submission over Loma Lookboonmee. She will miss the remainder of 2026 under the suspension and cannot return to competition until mid-February 2027.
