Mackenzie Dern remained a perfect 4-0 thanks to her first-round submission victory over Mandy Polk in October. It was the 24-year old’s second submission win in her young pro MMA career. The Brazilian-American risks that perfect record this Friday when she takes on Kaline Medeiros (8-5) at Invicta FC 26.
Dern’s Brazilian jiu-jitsu credentials rank among the most impressive of any grappler to enter the world of professional MMA. The black-belt has gold medals from the ADCC Submission Wrestling World Championship, World Jiu Jitsu Championship, Nogi Jiu-Jitsu Championship, Pan Jiu-Jitsu Championship, and World Professional Jiu-Jitsu Cup.
