Invicta FC 20: Evinger vs. Kunitskaya was a mixed martial arts event that was headlined by Invicta FC bantamweight champion Tonya Evinger defending her title against Russian newcomer Yana Kunitskaya. In the co-main event, strawweight champion Angela Hill will defend against Kaline Medeiros. In the controversial main event, Kunitskaya made Evinger submit to an armbar in the first round after the referee forced Evinger to move from a legal position leading to the submission. Evinger appealed the loss two weeks later and the Missouri athletic commission overturned the decision to a no contest.
