The UFC's return to Sao Paulo comes with a set of prelims that might have as many highlights as the main card. It might not be the most exciting affair in practice, but the featured prelim is an important one for the welterweight division, as rising Russian grinder Rinat Fakhretdinov looks to keep his momentum going against perennial tough out Elizeu Zaleski dos Santos. Light heavyweight prospect Vitor Petrino, who's in action against Modestas Bukauskas, has one of the highest upsides on the card, and Angela Hill's bout against Denise Gomes is a crucial veteran-versus-prospect test.
