But before "Cupcake" throws down against the gritty Brazilian, take a trip back to see how Tate obtained UFC gold for the first time with her upset victory over Holly Holm at UFC 196 on March 5, 2016, also in "Sin City."
Going into the final round, Holm was in control of the fight, as many had her winning the five-round title fight on the scorecards. Short of getting stopped, Holly was on her way to her first-ever successful title defense.
Tate, though was not going to be denied.
After taking the bout to the ground, Miesha locked in an air-tight rear-naked choke which forced the referee stoppage, though the "gangster" champion didn't tap. Now, Tate looks to be the first women ever not named Ronda Rousey to defend the 135-pound strap.
