In February 2019, Dern announced that she had put her MMA career on hold due to pregnancy. Her daughter, Moa, was born on June 9, 2019.
According to Dern, she left Black House MMA after a reported incident concerning her original coach, Juan Gomez, where he got into a physical altercation with her husband over a disagreement about money. However, Gomez disputed money being the reason and subsequently both Dern and her husband were asked to leave the team.
MMA fighter Mackenzie Dern has suffered the first defeat of her UFC career after stepping into the octagon just four months after giving birth.
The 26-year-old American, who gave birth to daughter Moa in June, resumed her UFC career today at UFC Tampa, where she was outclassed by Amanda Ribas.
The 26-year-old Brazilian won the decision with all three judges ruling 30-27 in her favour.
The loss means Dern now has a 2-1 record while Ribas moves to 2-0.
