Even though Israel Adesanya vs. Paulo Costa marks only the second time in UFC history where two undefeated men meet for a championship belt, that doesn’t mean neither has tasted defeat in MMA. “Borrachinha” does hold an impressive 13-0 record going into the UFC 253 main event Saturday night in Abu Dhabi, and that zero still stands only because The Ultimate Fighter bouts are not considered official bouts.
The year was 2014 and Costa was one of 32 fighters looking for a spot on the third season of TUF: Brazil.
