South Korea's Park will shake up the official UFC flyweight rankings if he knocks off Japan's Taira (No. 6). Park (10-0) has stopped five opponents under the UFC umbrella, including two appearances on the "Road to UFC" series. Taira (16-1) needs to bounce back after narrowly losing a late Fight of the Year entry against Brandon Royval in November.

Short notice, no problem. HyunSung Park is confident he won't need judges to win the UFC on ESPN 71 main event.
