Joanna Jedrzejczyk had a painful and brutal end to her fighting career after Zhang Weili knocked her out in their UFC 275 showdown on Saturday.

Weili pulled off one of the best wins of the night after she sent Jedrzejczyk to the floor face-first with a spinning backfist. After a strong first round where Weili controlled proceedings with her wrestling, things got more heated in the second with a flurry of exchanges between the two.

With 2:34 to go, though, Weili caught Jedrzejczyk with her spinning backfist to end the UFC 275 match … and her opponent's career.

Joanna Jedrzejczyk announced her retirement after the devastating defeat to Zhang Weili. She got a bit emotional as she held back her tears, even apologizing to Dana White and the rest of the organization for letting them down.

As she revealed her decision to the fans in attendance for UFC 275, she also shared what she plans to do next–including her dream to become a mother and a businesswoman.

“It's been 20 years,” Jedrzejczyk said, per ESPN. “I'm turning 35 this year. I want to be a mom. I want to be a businesswoman. I've been training more than half of my life. I love you guys.”

White, for his part, had nothing but praises for Jedrzejczyk as he thanked her for her work with the promotion and helping it grow.

“She was such a huge part of the growth of women’s MMA and it was incredible to have her be a part of this company. We will all miss her!” White told Yahoo Sports.
