While Jedrzejczyk has experienced a few minor hiccups in her fights, she's been fairly dominant during her reign as champion while taking out every contender the division has thrown at her including two wins over highly touted grappler Claudia Gadelha.
Jessica Andrade is challenging UFC Women's Strawweight Champion Joanna Jedrzejczyk for the gold at UFC 211.
A history lesson, albeit a brief one: Joanna Jedrzejczyk hasn't been considered an underdog in the UFC since first challenging for the strawweight title back at UFC 185 in March 2015.
Andrade is expected to take on Jedrzejczyk for the strawweight title at UFC 211, on May 13, in Dallas, Texas.

The main card will also feature a pivotal, welterweight fight between Demian Maia and Jorge Masvidal. "But I'm happy that UFC did this move". Jessica didn't face someone tough like me, so I will let her taste the power of my fists.
Then the fight started and just about everything changed.
Since coming down from bantamweight to fight at 115 pounds, Andrade has torn through every strawweight who has been put in her way. She has also taken pride in using any pre-fight slights from opponents regarding certain aspects of her skill set in order to improve them.
Despite the fact that her fighting future remains unclear, Rousey is a role model and ground-breaker, but with the record in sight Jedrzejczyk wants to - in her own words - "become an idol for herself".

Andrade stands in the Polish champion's way and Jedrzejczyk acknowledges that the Brazilian will arguably be her hardest test in the division. "I'm not as technical as her, probably won't ever be because that's not the game that works for me", Andrade said. "I like to challenge myself and do some new stuff in my life and explore new things". No, the best female fight in UFC history is an artist whose medium is pain and whose name is comically hard to say. Jedrzejczyk is vulnerable. She literally gets hit all the time, just like Conor McGregor, and she pumps her fist with a scream when she dominates a round.
A little over two years ago, the Pettis brothers arrived in Dallas on top of the world.
Everything that's come since then has had a similar feel - save for the underdog role.
First, Sergio Pettis - the younger of the two - was knocked out cold by Ryan Benoit, while his brother Anthony Pettis would hand the UFC's lightweight title to Rafael dos Anjos a couple hours later. But the news was released prematurely, according to UFC president Dana White, who said the company hasn't officially signed off on it.
