Digest more
Khamzat Chimaev has fired back at Paulo Costa after the latter accused him of DMing his partner.
Costa (14-4 MMA, 6-4 UFC) and Chimaev (14-0 MMA, 8-0 UFC) were booked to fight at UFC 294 in October 2023, but Costa wound up withdrawing due to injury. Their rivalry dates back to a heated run-in at the UFC Performance Institute in Las Vegas prior to Chimaev's UFC 279 win over Kevin Holland in September 2022.
