The UFC announced a few week's ago that Nate Diaz would be returning to fight Matt Brown at UFC 189. However, Diaz claimed just days after that the UFC was planning on him fighting former Lightweight champion Anthony Pettis.
Also, Diaz claimed on that the UFC announced the Matt Brown fight without him knowing. He said that he was supposed to fight Pettis at the event.
Now, Matt Brown has confirmed that he is indeed not fighting Diaz.
