null: With a combined five wins in their last seven bouts, respected middleweights Derek Brunson and Ed Herman are closing in on a spot in the top 15, and the winner of tonight's bout may determine who makes that move first. Owner of Octagon victories over Chris Leben, Brian Houston and Lorenz Larkin since coming to the UFC in 2012, Brunson is getting better with each bout, a progression that is coming at precisely the right time. A finalist on season three of The Ultimate Fighter, Herman has seen it all on fight night, and gritty wins over Trevor Smith and Rafael Natal have him ready to push Brunson to the limit.
