Joanna Jedrzejczyk lost to Rose Namajunas at UFC 217
Joanna Jedrzejczyk's effort to tie Ronda Rousey's record for most title defenses by a woman fell short, as she was defeated by first-round TKO by Rose Namajunas at UFC 2017.
The Polish star came into the fight with a perfect 14-0 record, but it was Namajunas who came out on the front foot. Namajunas knocked Jerdzejczyk down early in the round then struck her with a punch later in the round that caused the referee to stop the fight.
Jerdzejczyk was going for her sixth straight successful title defense.
