An updated list of active undefeated fighters with more than 10 wins competing in major promotions has been released, with Khamzat Chimaev's entry now marked with his first defeat. Chimaev's record of 15-0 has been updated to 15-1 after he lost by split decision to Sean Strickland at UFC 328. The comprehensive list tracks fighters who haven't competed in over two years or retired, and includes records verified through both Tapology and Sherdog. Chimaev was previously one of the most prominent names on the undefeated list. The loss represents a significant shift in his career trajectory. Other notable undefeated fighters on the list include Movlid Khaybulaev (24-0-1-1NC), Usman Nurmagomedov (21-0-1NC), Movsar Evloev (20-0), and Ilia Topuria (17-0).
Khamzat Chimaev's perfect professional record came to an end on May 9, 2026, when Sean Strickland defeated him by split decision at UFC 328, handing "Borz" the first loss of his career.
Chimaev, 32, had entered the fight as the number-one ranked middleweight and the number-ten ranked pound-for-pound fighter in the world. Representing the UAE and training out of Allstars Training Center, the six-foot-two fighter carried a record of 15-0 into the bout, built on a relentless combination of elite grappling and powerful striking. His 5.29 takedowns per 15 minutes rank among the most aggressive in the division, and his 60 percent striking accuracy underscored how rarely he wasted offense. His record now stands at 15-1.
Strickland, the reigning middleweight champion, improved to 31-7 with the victory. The 35-year-old from the United States trains out of Xtreme Couture and has long been one of the division's most durable and high-volume strikers. His output of 6.04 significant strikes landed per minute is exceptional at championship level, and his 76-inch reach gives him a persistent range advantage. The southpaw-troubling orthodox stance and ceaseless forward pressure have defined his title reign.
Why it matters
- Chimaev loses his undefeated status and drops from the top spot in the middleweight rankings, reshaping the division's landscape heading into the second half of 2026.
- Strickland's title defense against the most feared contender on the roster adds significant weight to his championship credentials.
- The result removes Chimaev from a short list of high-profile undefeated fighters in major promotions that still includes Movlid Khaybulaev (24-0-1-1NC), Usman Nurmagomedov (21-0-1NC), Movsar Evloev (20-0), and Ilia Topuria (17-0).
- A split decision outcome leaves the door open for a rematch conversation in the middleweight title picture.
