Ukrainian flyweight Maryna Moroz has been suspended for one year following a violation of the UFC Anti-Doping Policy, the promotion announced Tuesday. The 33-year-old fighter tested positive for meldonium, a banned substance classified as a hormone and metabolic modulator, during two separate out-of-competition drug screenings conducted earlier this year.

Combat Sports Anti-Doping (CSAD), which administers the UFC’s anti-doping program, collected samples from Moroz on June 25 and July 16, 2025, both of which returned positive results for the prohibited substance. The organization determined that both findings constitute a single violation since Moroz was not notified of the first positive test before providing the second sample.
