Ranked Strawweight Jaqueline Amorim Fails Drug Test for Ostarine

Ranked UFC strawweight contender Jaqueline Amorim has been flagged for an anti-doping violation. According to the UFC-funded Combat Sports Anti-Doping (CSAD) agency, Amorim failed two out-of-competition drug tests conducted on July 29 and August 17, 2026.

Both samples returned positive results for the presence of Ostarine. Under current agency protocols, the two positive tests will be treated as a single violation. While further details regarding the exact length of any potential suspension or administrative repercussions remain pending, the substance has been previously identified in cases of contaminated supplements within the promotion.

Amorim's inclusion in the anti-doping testing pool and subsequent failed test marks another instance of the promotion grappling with Ostarine-related violations, a substance notably involved in past cases concerning high-profile fighters like Sean O’Malley. The CSAD continues to oversee testing procedures for all active UFC roster members, with this development likely to impact the strawweight rankings moving forward.

Fantasy players should remove Amorim from upcoming lineup considerations, as her status for future bouts is now uncertain pending the conclusion of the CSAD disciplinary process.
