According to Sherdog and Wiki: 32-2-1(NC) http://en.wikipedia.org/wiki/Renan_Barão According to UFC homepage: 34-2-1(NC) (I added yesterdays loss) http://www.ufc.com/fighter/Renan-Barao What are these 2 wins?
Unnamed UFC bouts. There was an MMA fighter out of Mongolia, Goika Moto, who just retired 67 - 0. But all of his wins were against nobodies and he doesn't even show up on most popular MMA websites. Point is, UFC probably knows someone about these guys that we don't.
Matt Serra and Rashad had some ridiculous records on the UFC site back in the day too. UFC is less reliable than Wiki. Which is sad.
UFC makes plenty of mistakes with records. They showed Teixeira as 22-2 on the official LHW rankings last night but hes 22-3.
