Ailin Perez Misses Weight, Then Submits Zhelezniakova
Ailin Perez weighed 136.5 pounds for her bantamweight bout with Daria Zhelezniakova in Paris on September 27, 2024—half a pound over the 136-pound non-title limit. The fight went ahead, and Perez submitted Zhelezniakova with an arm-triangle choke at 3:52 of Round 1. The official weigh-in results and event scorecards document the miss and finish.
The weigh-in and the result
The half-pound overage was a documented weigh-in result; it does not establish anything about Perez’s health or how the bout would unfold. Zhelezniakova weighed 135 pounds, and the contest remained scheduled. Perez settled it quickly on fight night, using an arm-triangle choke to earn the first-round submission.
Perez’s run since Paris
Perez followed the Paris win with a unanimous decision over Karol Rosa in January 2025. She later beat Macy Chiasson in February 2026 and Norma Dumont in September 2026, extending her winning streak to seven. Her official record lists the recent result, and the promotion’s scorecards show all three judges gave her the Dumont bout 29–28.
A weigh-in detail, not a prediction
The Paris scale reading remains part of the bout’s record, but Perez’s performance is defined by what happened in the cage: a first-round submission victory. Her later wins have extended that momentum.
