An updated list of undefeated fighters with over 10 wins in major organizations shows Khamzat Chimaev has been removed after his split decision loss to Sean Strickland at UFC 328. Chimaev's record now stands at 15-1, ending his previously unblemished professional MMA career. The comprehensive list tracks fighters who have been active within the last two years and haven't retired, with records verified through Tapology and Sherdog. Notable fighters remaining undefeated include Movlid Khaybulaev at 24-0-1-1NC, Usman Nurmagomedov at 21-0-1NC, and Ilia Topuria at 17-0. The list also includes several other prospects across various weight classes and organizations including UFC, Bellator, PFL, and ACA.
Khamzat Chimaev's unblemished professional record came to an end on May 9, 2026, when Sean Strickland claimed a split decision victory at UFC 328, stripping "Borz" of his undefeated status and removing him from the ranks of major-organization fighters with ten or more wins and a perfect record.
Chimaev, 32, entered the fight as the number-one ranked middleweight and tenth in the pound-for-pound standings, carrying a 15-0 record that had made him one of the most discussed unbeaten fighters in the sport. The UAE-based Allstars Training Center product had built that reputation on elite grappling — averaging 5.29 takedowns per 15 minutes — combined with a striking accuracy of 60 percent. His record now sits at 15-1.
Strickland, the reigning middleweight champion, improved to 31-7 with the victory. The 35-year-old American out of Xtreme Couture is six-foot-one with a 76-inch reach and has long been known for relentless forward pressure, averaging 6.04 significant strikes per minute across his career.
With Chimaev's removal, the updated tracker of active undefeated fighters with more than ten wins in major organizations now highlights names such as Movlid Khaybulaev at 24-0-1 with one no-contest, Usman Nurmagomedov at 21-0 with one no-contest, and Ilia Topuria at 17-0 — though the verified fighter data here shows Topuria's record at 17-1, placing him outside the unbeaten group as well. The list spans multiple promotions including the UFC, Bellator, PFL, and ACA, and only counts fighters who have competed within the last two years and have not retired.
Why it matters
- Chimaev's loss ends one of the most high-profile unbeaten runs in recent UFC history
- The middleweight division's number-one contender now carries a defeat heading into any future title picture conversations
- Strickland's title defense reinforces his position atop a crowded 185-pound landscape
- The broader undefeated tracker continues to shrink as top prospects face elite competition
