Even Diaz's most ardent supporter (his trainer and manager Cesar Gracie) had enough. Failing to catch a flight to Las Vegas for a run-of-the-mill news conference to promote his title shot at UFC 137 against GSP, Zuffa came down with a dramatic decision to cast the pride of Stockton, Calif., aside. There would be no title shot for Diaz. A series of events unfolded from there, including Diaz testing positive against for marijuana metabolites (he's suspended until February 2013 by the Nevada State Athletic Commission) and Carlos Condit sits poised to fight GSP in November.
