Chimaev loses undefeated record; updated list of unbeaten fighters with 10+ wins

The undefeated era of Khamzat Chimaev came to an end at UFC 328 on May 9, when Sean Strickland handed "Borz" his first professional loss via split decision, reshuffling the list of active unbeaten fighters with ten or more wins across major promotions.

Chimaev, 32, had long been regarded as one of the sport's most complete prospects. The UAE-based middleweight carried a record of 15-1 heading out of the bout and entered ranked first in the division and tenth pound-for-pound. His statistical profile was remarkable — a 60 percent striking accuracy mark and an elite 5.29 takedowns per 15 minutes made him a genuine two-way threat. That loss now removes him entirely from the undefeated conversation.

Strickland, the reigning middleweight champion, improved to 31-7. The 35-year-old American, who trains out of Xtreme Couture and fights out of an orthodox stance, brings relentless pressure with 6.04 significant strikes landed per minute, doing so at a six-foot-one frame with a 76-inch reach.

Why it matters

• Chimaev's first loss reshuffles the middleweight title picture, with the division's top-ranked contender now carrying a blemish on his record.
• The updated unbeaten list now features Movlid Khaybulaev (24-0-1-1NC), Usman Nurmagomedov (21-0-1NC), Movsar Evloev (20-0), and Ilia Topuria (17-0) as the most prominent names across UFC, Bellator, PFL, and ACA.
• Baysangur Susurkaev moved to 12-0 with a submission win at UFC 328, while ACA newcomer Alikhan Musaev entered the conversation at 11-0 following his win over Furkhat Komilov at ACA 203.
