Jones claims retirement, Costa targets Russian opponents, Merab plans two more fights

A collection of MMA news items: Johnny Walker gave Jiri Prochazka a surprise gift ahead of his daughter's birth. Jon Jones stated he has hung up his gloves and is now only a businessman, not a fighter. Paulo Costa reversed his previous stance and now says he hates Russian fighters, claiming Murzakanov will be his second straight Russian opponent, with Khamzat Chimaev to follow. A video from Costa's team showed him struggling to make 93 kg, despite previously competing at 84 kg. Josh Hockett dropped his over-the-top persona after filming and apologized to those present. Merab Dvalishvili plans to fight twice more this year despite a broken nose. Both Jiri Prochazka and Carlos Ulberg successfully made weight at the ceremonial weigh-in.
