After a long but influential MMA career, 41-year old Pedro Rizzo (20-11) decided to call it quits after his win over Andrew Flores Smith at Face to Face 12 in Brazil. Prior to the fight, Rizzo had taken two years off from fighting but was able to get in one last bout before leaving the sport forever.
After leaving the UFC, Rizzo was a lot less successful, compiling a record of 6-6. In his defense, Rizzo continued to fight respectable talent after his good years were behind him. His six losses came against Sergei Kharitonov, Roman Zentsov, Josh Barnett, Gilbert Yvel, Fedor Emelianenko and Satoshi Ishii.
