Diaz was confident coming into the bout but was unable to achieve success in the match, ultimately losing to Sanchez by unanimous decision. During the televised post-fight interview in the octagon, Diaz continued the controversy by declaring that he respected Sanchez fighting ability but did not think he deserved to be there, despite Sanchez's win. Diaz's next fight was against Joe Riggs at UFC 57. Similar to his treatment of Sanchez, Diaz made sure that he taunted his opponent plenty before their fight starting at the official press conference at the event in which Diaz confronted Riggs and the two exchanged words. They continued their conversation at the official weigh-ins in which both fighters had to be separated by UFC president Dana White and other officials present.
