With Veronica Macedo injured, KSW women’s flyweight champion Ariane Lipski will make her octagon debut against Maryna Moroz at UFC Fight Night 140 in November.

MMAjunkie verified the matchup between Lipski (11-3 MMA, 0-0 UFC) and Moroz (8-3 MMA, 3-3 UFC) with a person close to the situation. The person wished to remain anonymous because the matchup hasn’t been made official by UFC. Combate.com first reported the news.

UFC Fight Night 140 takes place Nov. 17 at Parque Roca Arena in Buenos Aires, Argentina. The event is expected to air on FS1 following early prelims on UFC Fight Pass, though broadcast plans haven’t been finalized.

Lipski, 24, will vacate her 125-pound belt from KSW to join the UFC roster. The Brazilian has won her past nine bouts and has earned eight of her 11 career victories by stoppage. She reportedly became a free agent following her most title defense with March and apparently turned down a renewal offer from KSW.

Moroz, 27, enters the event on a two-fight losing skid. After beginning her career with six victories in a row, the Ukrainian fighter has fallen on a rough patch with three defeats in her past six contests.

The latest UFC Fight Night 140 lineup now includes:

Neil Magny vs Santiago Ponzinibbio
