His life is ‘a living hell’ so Nick Diaz is going to box Fernando Vargas?Steve CofieldCagewriterApril 15, 2011This latest gem doesn't sound like Nick Diaz is "playing the game." as Dana White requested last year.Outside the cage, that means the Strikeforce welterweight champ, has to show up for drug tests and fulfill some of his media responsibilities. Do that and there could be huge paydays awaiting him in the UFC. Oh, and one more thing ... don't sign boxing contracts.The constantly displeased Diaz told HDNet there's no one for him to fight in Strikeforce and his life is a living hell. His trainer Cesar Gracie says the MMA star has signed a deal to fight former world champion boxer Fernando Vargas in September. Gracie says the Diaz camp is just waiting for Vargas, 33, to sign the contract.Update - Camp Diaz says the Vargas fight is off: "We were talking about Vargas, but the thing is, I just came under some information that Vargas apparently has some kind of medical issue where he's not able to pass the test any more, and he could be retiring," Gracie said. "Vargas was very interested, but unfortunately, if he can't pass the test, he can't pass the test."Gracie says now Diaz wants to fight Jeff Lacy.This is all an interesting development since Scott Coker has basically indicated Diaz can't box while under contract with Strikeforce.Vargas claims he's making a comeback and told ESPN.com's Brett Okamoto in January that he had his weight down to 187 pounds. If his goal is to make a run at a world title again, why would Vargas risk his reputation by fighting someone from the MMA world? Who wants to bet this "dream" fight never comes off?
