I had posted about that here a long time ago lol. JJ said that in 2021 in the Joe Rogan podcast. Joe asked if he were outperformed and he said he was training in Chechen and this guy, who was the original wolf, hit him with a spinning pack kick to the liver and he was knocked down and couldn't breath for some time. Then people there even called this Amagov to a podcast and he said : "Yeah, but we have been training together a long time, ever since 2010. It was sparring too, so I don't know why JJ brought it up, it doesn't mean much. I like the guy, but I think he pushes too much sometimes, I worry that he can't live without having a fight booked lol. But he comes here to the gym to train and I like him and his dedication "
The guy who ran the gym, after JJ told it in the podcast, confirmed it, and the gym is like a mysterious and rough gym on Chechen that ots been reported to hold contents of fights like a fight club almost, said that JJ would go there to spare and they would always welcome him, and that he (the owner) was upstairs and heard someone screaming out loud, the roar of a man and he was afraid someone was stabbed. Then he said it was JJ laying on the ground. He said that right after irl JJ came back to sparring but started to go serious, trying to pay back, and then he'd spar one guy after another and that people enjoyed it because it became almost like a real 1 round striking fight, but whenever JJ was done "sparring " with one after 5 minutes, the fighters would be looking at each other like "you go next! "
I had posted the interviews in the thread it was brought up past year.
Maybe that's like how Chimaev has a connection to JJ too. Khamzat said more than one time that JJ is the GOAT and also, his favourite fighter.
