It was previously officially confirmed that the famed American fighters will meet on November 16 in the main event of UFC 309 in New York City.
"Jon and I have been sitting next to each other [in the cageside at UFC 306] and we've been discussing the possibility of training together for a while now. I think it's going to happen. His fight is coming up in November. And it takes me about a week or two to recover from the fight. So I think we'll have enough time to train together. I feel like a heavyweight and he feels like a heavyweight. John looked more fit compared to how he looked last fall. I'd like to learn from his experience. I don't know if we will meet in the octagon, but I would like to get the experience of training with him," said the Brazilian in an interview with YouTube channel Full Send MMA.
