This Saturday, former UFC strawweight champion Joanna Jedrzejczyk faces a tough challenge in Tecia Torres.

Jedrzejczyk and Torres will be part of the UFC on FOX 30 main card live on FOX from Calgary, Alberta, Canada.

With Rose Namajunas holding court in the division after back-to-back wins vs. Jedrzejczyk, this is a key fight for the fighter formerly known as “Joanna Champion.”

From 2015 until last November, Jedrzejczyk appeared untouchable. She dominated her way to wins over the likes of Jessica Andrade, Karolina Kowalkiewicz, Claudia Gadelha, Valerie Letourneau and Jessica Penne after finishing Carla Esparza to claim the title.

But at UFC 217, all that mystique was lost when Namajunas finished her. The champion went on to defend her title in April with a convincing decision, sending Jedrzejczyk to the challenger road once more.

Torres is no slouch and will present a tough opponent for the fighter. She is a former contestant on The Ultimate Fighter, losing to Esparza after returning to action.

With wins over Paige VanZant, Felice Herrig, Angela Hill and the current champion, Namajunas back in 2013, it is not a tough sell to say Torres is looking to challenge for the belt.

She did drop a rematch with Namajunas in 2016 and is coming off a loss to Jessica Andrade that stopped a three-fight win streak, but at 10-2 overall, Torres is on the short list of contenders.

For Jedrzejczyk, this is a make-or-break fight. Win, and she is likely stil viewed as the No. 1 or 2 ranked contender behind Namajunas. Lose, though, and the road gets bumpy and littered with hills and valleys moving forward.
