[2] Yarbrough was a star running back for the Central Cal War Angels of the Women's Football Alliance until the team was dissolved in November 2017.
Yarbrough has been an outspoken advocate for her WMMA division: “Personally, I feel MMA fans outside the United States are more accepting of female heavy- and open weight fighters.
I hope and believe that the women’s heavy- and open weight divisions will grow via depth in fighters, fans, popularity, and significance.
I feel at this moment we are seen as a “joke” in the sport; there are promoters, organizations, and people who see us as “fat chicks” – unpleasant and distasteful to their eyes.
We will not stop paving this road until we can claim a championship belt.”[4] For her first heavyweight fight, Yarbrough faced Crystal Parson at The Warriors Cage 24 in Porterville California on April 1, 2016.
