Diaz’s manager Cesar Gracie tells "Inside MMA" that Diaz has signed a boxing contract to fight Fernando Vargas later this year. The contract is awaiting Vargas’s signature, but Gracie says that unless Dana White offers Diaz a fight with Anderson Silva, Nick’s next fight will definitely be in boxing.
Nick Diaz - "(Strikeforce) doesn't have anybody else for me to fight right now, I'm better than all these guys they have. The guys they have ranked above me, I'm sure they don't want to fight me. I don't see much of a future in this sport for me. I honestly don't, especially if there's not a whole (lot) of money going on."
