Hamzat Chimaev's previously unblemished record has been updated following his split decision loss to Sean Strickland at UFC 328. The comprehensive list tracking active fighters with over 10 wins and no losses in major promotions has been revised to reflect Chimaev's first defeat, changing his record from 15-0 to 15-1. The list, which uses Tapology records cross-referenced with Sherdog, includes fighters who have been active within the past two years and haven't retired. Chimaev had been among the elite group of undefeated fighters before this setback. The updated rankings show numerous other undefeated fighters across various weight classes and promotions, with Movlid Khaybulaev leading at 24-0-1-1NC.
Sean Strickland successfully defended his middleweight title at UFC 328 on May 9, earning a split decision victory over Hamzat Chimaev and handing the Chechen-born contender the first loss of his professional career.
Strickland, now 31-7, entered the fight as the reigning middleweight champion at 35 years old. The American fighter out of Xtreme Couture is known for his relentless output, averaging an impressive 6.04 significant strikes landed per minute, with a 76-inch reach that allows him to control range from his orthodox stance. He stands six-foot-one and represents one of the division's most durable and high-volume strikers.
Chimaev, who came in riding an unblemished 15-0 record, saw that streak come to an end on the night. The loss moves him to 15-1 and removes him from the short list of elite undefeated fighters with more than ten wins competing in major promotions. He had long been considered one of the most dangerous unbeaten prospects in MMA, but Strickland's championship experience proved to be the difference across the judges' scorecards.
Why it matters
- Chimaev's first professional loss reshuffles the middleweight title picture and resets expectations around his contender status.
- Strickland's split decision win, while not a dominant finish, reinforces his grip on the 185-pound title.
- The result highlights the striking volume and championship-level consistency that Strickland brings, averaging over six significant strikes per minute over the course of his career.
- With Chimaev now at 15-1, the division's undefeated contender conversation shifts toward other fighters, including Movlid Khaybulaev at 24-0-1-1NC across promotions.
