VIDEO | Mackenzie Dern scores a nasty first-round submission victory in flyweight debut

Mackenzie Dern improved her mixed martial arts record to a perfect 4-0 at Friday night’s LFA 24 event, scoring a first-round submission victory over Mandy Polk. After unfortunately missing weight in her last two bouts, a 2016 Submission of the Year contender over TUF 26 competitor Montana Stewart at Legacy FC 61, and a decision defeat of Katherine Roy at LFA 6, Dern seems to have found the perfect home at flyweight.

Dern’s opponent, Mandy Polk, fell to 3-4 with the loss. Polk, who made her MMA debut in 2014, was riding a three-fight streak into her fight with Dern, defeating Briannah Conatser, Anne Malinoff and Ronni Nanney, and most recently lost to Katy Collins. 

The former Brazilian jiu-jitsu world champion, Dern, has stated in previous interviews that she plans to make her UFC debut in 2018.
