Nate Diaz (Esther Lin/MMA Fighting)Nate Diaz Set to Return to Welterweight Against Matt Brown at UFC 189 José Youngs April 8, 2015 Events, News, Spotlight It looks like the UFC’s welterweight roster will have to deal with two Diaz brothers now. On Wednesday night, during an episode of UFC tonight it was announced former UFC lightweight contender Nate Diaz will be making the move up to welterweight to face Matt Brown at UFC 189 this summer. Diaz (17-9), winner of the fifth season of The Ultimate Fighter previously competed as a member of the UFC’s 170-pound division between 2010-2011. During this run, he picked up an impressive third round submission over Marcus Davis before dropping back-to-back decision to Rory MacDonald and Dong Hyun Kim, prompting the drop back down to 155-pounds. In his last outing, fans saw him on the receiving end of a one sided decision loss to current UFC lightweight champion Rafael dos Anjos at UFC on FOX 13 in December. This marked his first appearance inside the Octagon since his first round TKO victory over Gray Maynard in the main event of TUF 18 Finale in November 2013. During his hiatus, he spent much of his time in the middle of a contract dispute with the UFC. He will enter this bout with 11 career submission victories, eight of which have come under the UFC banner. Brown (19-12), a veteran of the seventh season of The Ultimate Fighter, will be looking to get back into the win column after dropping his last two bouts to former champion Johny Hendricks and reigning champion Robbie Lawler. Prior to these two setbacks Brown put together a career seven-fight streak, which included five straight by way of knockout and two Fight of the Night bonuses. He will enter this bout with 17 career stoppage victories and a UFC record of 12-7. UFC 189 is currently scheduled to take place on July 11 at the MGM Grand in Las Vegas. A featherweight title fight between 145-pound kingpin Jose Aldo and Irish megastar Conor McGregor will serve as the headlining act while a welterweight title fight between newly crowned champion Robbie Lawler and Rory MacDonald will meet in the co-main event.
