Very controversy situation with Francis Ngannou. He is inactive for a year already. I hope he knows what he is doing. So far I havent heard he has signed different contract with anyone else. But I predict that promotions will now fight for him. UFC has made him famous. Now Francis is able to select an easy path - promotion with weaker heavyweight than UFC has, and sign a big contract with them. Beat few bags, grab billions and retire 
He's in a precarious place for sure. He can of course easily sign with any other MMA organisation but they probably won't pay him what he would have got with the UFC, though maybe one promotion might overpay for him and give him a massive bag to get the huge exposure and all eyes on them to take away some market share from the UFC so it might pay off that way. Hopefully he gets a mega crossover boxing even with someone like Fury which there was certainly talks behind the scenes about and Fury even posted something on his Instagram recently about it now Francis is a free agent. Making that fight is easier said than done though because everyone wants to fight Fury so he's in demand and will have a lot of mandatory challengers queuing up to fight him which he will have to take. I dare say there will likely be a Usyk rematch as well along with potential fights with AJ and Joe Joyce so it could be years before he's free. In this situation, I believe the UFC actually has the upper hand. Because even if he does decide to boycott the UFC and go to any other fight club, he is not going to get more money compared to the UFC anyway. So in this case, that UFC has the upper hand.
He can certainly get more money by becoming a boxer. But that's another story. As far as the mixed martial art is concerned I do not think that anyone is going to pay him as the UFC does. Actually, I am sure that no one is going to pay him like the UFC. So this decision might actually be bad for his future and carrier. It will be better if both Francis and the UFC can come to a common ground.
