Yesterday the UFC likely prompted smiles throughout the MMA world by announcing Matt Brown will fight Nate Diaz on July 11th, but according to the latter, he never signed off on the bout.

If you missed, late on Wednesday the UFC announced that Diaz is returning to welterweight and that he’ll scrap Brown at UFC 189. It’s the latest big name bout to be added to the already stacked card. Sounds good right?

Well, after the announcement, Diaz tweeted “nah I’m fighting Pettis”. When the outspoken fighter was reached by MMA for a comment, Diaz claimed that he’s supposed to meet with the UFC on Monday to go over his next fight. Diaz furthered that since he’s been calling for a bout with Anthony Pettis, and vice versa, he thought that scrap was next. But, then came the UFC’s announcement…

Diaz also added: “I’m open to the Brown fight — I said I wanted to fight him last year — but I don’t like that they made the fight official before we ever negotiated or agreed to it.”

So, unless there’s been some sort of miscommunication here between Diaz’s reps and the UFC, this does seem odd no? Since Pettis is also coming off a decision loss to Rafael dos Anjos, a fight with Diaz made a lot of sense; it could have headlined a Fight Night card, no question.

Sure, most people probably aren’t complaining, however, since Brown-Diaz has the potential to be fantastic.  Brown is coming off a decision loss to Johny Hendricks in March.

UFC 189 will be headlined by a featherweight title fight between champion Jose Aldo and Conor McGregor. In the co-main event, welterweight champ Robbie Lawler will take on Rory MacDonald.

Some of the other bouts that have been booked for the card include Mike Swick vs. Alex Garcia, Dennis Bermudez vs. Jeremy Stephens, Brandon Thatch vs. John Howard and Gunnar Nelson vs. John Hathaway.
