One of the best women's MMA fighters of all time will retire.

The former UFC women's strawweight champion announced her retirement Saturday following a knockout loss. If she beat Zhang, she would have been in line for a title shot but she was thrown out in the second round by a back fist.

After the fight, she took off her gloves and said she was quitting.

She said it's been two decades. I will turn 35 this year. I would like to be a mother. I would like to be a business person. I have been training for a long time. I adore you guys.

The most successful title defenses in the UFC women's strawweight division have been held by Jedrzejczyk. The first Poland-born UFC champion is tied with current champion Carla Esparza for the most wins in division history and has the most title fights in strawweight history.

The greatest women's MMA fight of all time has been called the greatest women's MMA fight of all time because of the split decision loss toZhang in the UFC 248 bout. She will end her career with a 10-5 record. After her debut in the UFC, she quickly won the hearts of fans with her striking style and charisma. The multiple-time Muay Thai world champion defeated Esparza for the title.

She told American fans that they could call her "Joanna Champion" even before she won the belt. She will have to change her nickname to "Joanna UFC Hall of Famer" in the near future because she is going to be there.
