Jon Jones is sharing his view on what happened to Nate Diaz on the set of ALF Reality, the Russian Ultimate Fighter clone currently being filmed in Thailand.

Jones and Diaz were set to coach opposite each other on the latest season of the show, which has previously featured Aljamain Sterling vs. Peter Yan, and Khamzat Chimaev vs. Arman Tsarukyan. But Diaz and his team stormed off set after regular series prankster Zalimkhan “Zalik” Yusupov kicked off a brawl on day one that reportedly involved ALF Reality crew members attacking members of Diaz’s entourage.

“We had one of our young fighters, a guy named Zalik,” Jones told Red Corner MMA. “He was playing with Nate. He wanted to play fight with Nate. Nate kind of came in a little bit on edge, I think he had some previous beef with some Russian fighters. So he was a little bit on edge when he got here.”

“Play fighting with Nate was was not the best idea. It became serious right away and we had to replace Nate.”

Zalik made headlines during filming of last season’s Russian TUF clone when he seemed to choke Aljamain Sterling unconscious. But more recent footage from that incident shows it was all part of a prank to stress out Petr Yan, who had guaranteed the safety of “Funkmaster” on set. After a tense moment for Yan (and an appearance from Hasbulla), Sterling ‘woke up’ and sang happy birthday to a relieved Yan.
