Undefeated strawweight phenom Mackenzie Dern (5-0) is set to make history this year, as she will become the first female in the history of MMA to have fights completed in all three of the sport's leading promotions -- Invicta Fighting Championships, UFC and Legacy Fighting Alliance.

The 24-year-old signed with the UFC earlier this week, according to a report from MMA Fighting. She's penciled in to compete against Ashley Yoder on March 3 in Las Vegas, as part of the UFC 222 pay-per-view. It hasn't yet been announced if she'll be on the main pay-per-view card, or featured in preliminary card action. What we do know is that her signing to the Las Vegas-based promotion puts her in extremely rarefied air. She will become the first woman to have fights completed with the top three organizations involved in the female side of MMA.

Dern's hotly-anticipated Octagon debut comes on the heels of an incredible five-fight stretch with LFA and Invicta FC, which included wins over "TUF 26" alum Montana Stewart and hard-hitting striker Mandy Polk. In her most recent start, the Phoenix native finished Kaline Medeiros via armbar at Invicta FC 26.

If all goes according to plan, Dern will become the first female to have LFA, Invicta FC and UFC fights on her resume. No one else in the history of MMA has accomplished the feat.

Andrea "KGB" Lee was supposed to beat Dern to the punch on the achievement, but her UFC debut was postponed. Lee has fights completed with Invicta and LFA, so her appearance at UFC 216 would have made her the first woman to compete for all three promotions. But with Lee's Octagon debut postponed until late-2018, Dern will become the first to notch the honor.
