Bellator is not an option. First of all they couldn't afford him, and secondly, Jones would probably lose out on alot of his sponsorship money because part of that is based on being in the UFC. His sponsors are going to pay him much less money if he goes to Bellator and would have to negotiate new contracts with them.
Plus Bellator just barely did 100k buys recently...how much more do you really think they could do with Jones? Its not like he has a huge fan base he's going to bring with him, and I doubt very many people want to see him ragdoll B and C level fighters.
Unfortunately, Jones has no real play here.
