Chimaev loses undefeated status with split decision loss to Strickland

Khamzat Chimaev's previously unblemished record of 15-0 came to an end at UFC 328 when he lost by split decision to Sean Strickland. This was Chimaev's first professional MMA defeat and removes him from the list of active undefeated fighters with more than 10 wins in major organizations. The list tracks fighters who haven't competed in over two years and haven't retired. Chimaev's loss is particularly significant given his meteoric rise and dominant performances prior to this setback. The updated rankings now show his record as 15-1.
