That isn't his fault lol. UFC/Dana all said they have a hard time getting fighters to accept a fight with Khamzat. Notice how all the fighters that usually say they are willing to fight him have all been quiet the last few months? That's because Khamzat has been looking for a fight for the past few months and UFC has been trying to get fighters to fight Khamzat for the past few months lol. Only one that agreed to it was Pereira but wanted it at LHW so the belt wasn't on the line since he has a rematch for the title already in place with Izzy.
Costa has contract dispute so he isn't fighting anyone until that's cleared up, that's why his fight with Whittaker got pulled. Notice anyone else speaking up?
