UFC heavyweight champion Jon Jones is no stranger to fist fights. He's competed 30 times in professional MMA and infamously brawled with Daniel Cormier at a UFC 178 media event. But Jones never witnessed anything like Nate Diaz's recent melee on a Russian reality show set.

Jon Jones has detailed Nate Diaz ’s exit from a Russian reality television show, on which the pair were working until the latter became involved in a brawl. The MMA show, which has been described as a Russian version of The Ultimate Fighter, is being filmed in Thailand, where chaos broke out on the set this week.

Diaz and Jones were filming the show in Thailand, doing team introductions, when Jones' fighter — 19-17 welterweight veteran Zalimkhan Yusupov — started instigating with Diaz. Soon after, a member of Diaz's team attacked Yusupov, which escalated the whole situation.
