Just an educated guess...
Alvarez wants to fight for the UFC. The UFC has offered Alvarez a deal that Bellator matched. Now the UFC has offered a better deal that Bellator does not want to match so now they're trying to get the UFC to abandon the offer by taking their sweet time to tell them they won't match the offer. If Alvarez fights before Bellator tells him they won't match the deal he gets sued for breach of contract. So now Eddie is caught between a rock and a hard place because if he doesn't fight he doesn't get paid but if he fights he's back in a deal with Bellator.
