Strikeforce welterweight champ Nick Diaz is tired of waiting for his shot at UFC welterweight champ Georges St-Pierre, and has threatened to leave MMA to do boxing for the ‘money‘ as of recent.

Interestingly thought the first figures of a 10 round boxing match bout between Diaz and Jeff Lacy by Boxing promoter Don Chagrin have been set at $175,000 for Diaz, which would be the same paycheck he made in his last bout against Paul Daley in Strikeforce. Lacy was even said to have done a 50/50 paycheck split just to ensure that the fight would take place.

Though Lacy is said to have signed on the dotted line, Diaz’s manager Cesar Gracie is still hopeful that the UFC will come around to stop the champ from signing and leaving the sport by giving in to his demands for a UFC title shot.

“Barring something like Dana White telling us, ‘Hey, we really need you to fight GSP at such-and-such a date and it conflicts with [boxing] – barring that, we’re going to fight Lacy,” said Gracie to MMAJunkie.

With Diaz’s current contract allowing a possible boxing match, could the Zuffa organization really sit back as one of the best in the sport leaves a title in his prime to help boxing pick up new MMA fans? Doubtful, but it may come down to a question of what fight makes more dollars and ‘sense.’ Since Anderson Silva vs GSP would equal bigger PPV buys than a Nick Diaz vs GSP bout, that may be what the UFC is considering at this point. This of course only possible if Silva defeats his next scheduled opponent Yushin Okami at UFC Rio.
