Jones announces retirement, Costa struggling with weight ahead of Murzakanov fight

Jon Jones has announced his retirement from fighting, stating he has hung up his gloves and will now focus solely on being a businessman. Paulo Costa's team released footage showing him struggling to make 93 kg, a significant increase from his usual 84 kg fighting weight, ahead of his bout with Azamat Murzakanov. Costa also made inflammatory comments about Russian fighters, promising to defeat Murzakanov and calling out Khamzat Chimaev next. Additionally, Merab Dvalishvili plans to fight twice more this year despite suffering a broken nose. Johnny Walker surprised Jiri Prochazka with a gift related to his daughter's upcoming birth, and both fighters were featured at the ceremonial weigh-ins.
