Unbeaten Legacy Fighting Alliance champion Sabina Mazo has her first UFC booking.
Mazo, 21, burst onto the regional scene with a pair of highlight-reel head kick KOs in 2017 before capturing the LFA flyweight title last April. The Colombian successfully defended her belt once before signing a four-fight deal with the UFC.
Moroz will be looking to snap a two-fight losing streak after dropping back-to-back unanimous decisions to Angela Hill and Carla Esparza. In six UFC fights, Moroz, who hails from the Ukraine, is 3-3. The 27-year-old made her debut in April 2015 with a first-round submission of Joanne Calderwood.
UFC Philadelphia will air live on ESPN.
