Brazilian flyweight Roque Conceicao Moreira Junior and Alexander Chavez collide in one of the smallest weight classes on the DWCS Week 9 card, with a UFC contract on the line for whoever makes the stronger impression. Flyweight is one of the UFC's thinner rosters, meaning a dominant performance in this division carries extra contract value beyond what Dana White sees in a single night.
