White says that McGregor cannot fight without UFC approval.
We haven’t spoken since [McGregor’s Manchester talk]..He came out and said ‘I can do this without them [the UFC]’ and I guarantee you he can’t do it without us. What I’ve said was that I’ve always been respectful of Conor with the things he wants to do and everything else but if he wants to go down that road it will be an epic fall. And everybody knows exactly what that means. I don’t think anything else needs to be said. That’s it…There’s nothing to talk about. Conor McGregor is under contract with the UFC. He’s out on maternity leave right now and after his girl has the baby we’ll offer him another fight.
