Maryna Moroz, a UFC women’s flyweight, accepted a one-year suspension on September 2, 2025, after testing positive for meldonium in two out-of-competition drug tests on June 25 and July 16, 2025, in Boca Raton, Florida. Combat Sports Anti-Doping (CSAD), the UFC’s drug-testing partner, issued the penalty, reduced from two years due to Moroz’s cooperation and medical documentation showing she used the substance under a doctor’s care. Moroz failed to notify the UFC or apply for a therapeutic use exemption, leading to the violation. She is eligible to return on July 17, 2026.
Suspension Details and CSAD Findings
Moroz tested positive for meldonium, a banned hormone and metabolic modulator. The two failed tests were treated as one violation since she wasn’t notified of the first result before the second test. She provided medical records showing a licensed physician prescribed meldonium for health issues, per CSAD’s statement.
CSAD noted Moroz’s oversight. She didn’t inform her doctor she was a tested athlete or check the UFC’s prohibited substance list. She also failed to request a therapeutic use exemption. Her cooperation and lack of scheduled fights during the period led to a one-year suspension, starting July 17, 2025.
Moroz has not competed since a split decision loss to Joanne Wood at UFC 299 in March 2024.
Maryna Moroz, 33, has an 11-6 MMA record, with 6-6 in the UFC. She turned pro in 2013 and joined the UFC in 2015, debuting with a 90-second armbar win over Joanne Wood at UFC Fight Night 64. Her notable wins include Mariya Agapova, Mayra Bueno Silva, and Sabina Mazo.Moroz competed at strawweight before moving to flyweight in 2020, where she went 3-3. Her recent losses to Jennifer Maia (2022), Karine Silva (2023), and Joanne Wood (2024) mark a three-fight skid. She trains at American Top Team in Boca Raton, Florida.
Moroz made headlines at UFC 272 in March 2022, submitting Mariya Agapova amid Russia’s invasion of Ukraine. She delivered an emotional speech about her family’s safety, with her father making “home grenades” to aid Ukrainian troops. The win earned her a $50,000 performance bonus.
In 2021, Moroz faced controversy when Agapova accused her of spreading lies about drug use and a knife threat, costing Agapova sponsorships. Moroz denied the claims, and their UFC 272 fight settled the rivalry. In 2022, Moroz became the first UFC fighter to pose nude for Playboy Centerfold, calling it a life-changing moment.
Her suspension aligns with other recent UFC drug test cases. Khalil Rountree received a two-month suspension in 2024 for a self-reported positive test due to a supplement error. Marcos Rogerio de Lima faced a one-year ban in 2025 for a second violation.
