Grasso submitted Shevchenko in the fourth round in March, ending the Kyrgyzstani fighter’s five-year reign atop the division – as well as her nine-fight win streak.
In doing so, 30-year-old Grasso became just the second Mexican champion in UFC history, and she is now her nation’s only reigning title holder.
Can Shevchenko, 35, reverse the result on Saturday? Fans will find out as she and Grasso headline a Fight Night event in Las Vegas – marking a rare move for the UFC, which typically saves title bouts for pay-per-views.
