After his UFC 318 win on Sunday, Middleweight contender Paulo Costa blasted Khamzat Chimaev for allegedly messaging his girlfriend, calling Chimaev a "coward" and vowing to chase him down. Costa claimed Chimaev told her to "find a better man." In response, Chimaev laughed off the accusation on X, saying, "It was she who wrote to me, habibi."
