That's because the former Strikeforce Welterweight Champion, who failed to get his hands around gold at UFC 158: "St. Pierre vs. Diaz" last month in Montreal, is likely to remain retired after his second straight loss inside the Octagon, according to a report from UFC Tonight.
When contacted by MMAmania.com, Jonathan Tweedale, attorney for Diaz, said his client's decision to retire was made during the UFC 158 post-fight press conference (watch it here) and was not "news." That should come as a relief to anyone who's grown weary of "Weight Gate."
Diaz returned to the Octagon in October 2011 after nearly a five-year absence, defeating former two-time champion B.J. Penn to put himself in position to challenge St. Pierre for the title. While "Rush" was on the shelf with kneehab, Diaz lost to Carlos Condit at UFC 143 and flunked his post-fight drug test.
It didn't keep him out of a title fight, but he was unable to capitalize on the opportunity.
In addition, his second run under the ZUFFA umbrella was plagued with public gaffes, run-ins with management and bizarre accusations. There's no guarantee Diaz will pass his latest drug test (his words, not mine), so it would not come as a surprise to learn that UFC President Dana White supports his decision.
Unless, of course, there's money like this to be made.
