Not even 24 hours after T.J. Grant was pulled from the UFC rankings, presumably due to his inactivity and uncertain future, former title challenger and long-time veteran Nate Diaz has also been dropped. Diaz was placed 5th after Grant's removal, and now everyone below Diaz has moved up one spot, with Joe Lauzon snagging the last ranked spot at #15.
This is an interesting situation that has developed. Unlike Grant, Diaz has actually fought fairly recently, stopping Gray Maynard in the TUF 18 Finale main event on November 30th, which is less than 6 months ago. In January, Dana White claimed that Diaz had turned down a fight with Khabib Nurmagomedov for April 11th, which both Diaz and his manager Mike Kogan denied. At the end of February, Diaz then asked for his UFC release right on the heels of the resolution of the Gilbert Melendez-Bellator-UFC triangle.
Last month, Diaz went on a tirade over his pay, demanding "more money", to which Dana White said "get back to work", and that he shouldn't be asking for "Justin Bieber money" after a singular win over Maynard snapped his two-fight losing streak. Just two weeks ago, White told the media at UFC 172 that Nate (but not Nick) was ready to fight and that Diaz had spoken to matchmaker Joe Silva.
We should note that there doesn't seem to be anything on the radar suggesting that Diaz has been removed from the UFC roster entirely, so for now it appears that his shiny new "unranked" status could be stemming from the never-ending butting of heads between the UFC's brass and the Diaz Brothers (with special guest appearances from Mike Kogan and Cesar Gracie). We'll see where this leads to next, as I'm sure Diaz will have something to say on this matter very soon.
