Ottow is filling in for Michael Graves, who was removed from the bout after being arrested on a misdemeanor battery charge last weekend. UFC Fight Night takes place at Ibirapuera Gymnasium in Sao Paulo and is headlined by a light heavyweight tilt between Antonio Rogerio Nogueira and Ryan Bader.
Ottow had success in his short-notice promotional debut, taking a split-decision victory over Octagon veteran Joshua Burkman at UFC Fight Night in Portland on Oct. 1. “The Barbarian” is 14-3 as a professional, with 10 of those wins coming via submission.
Moraes is unbeaten in his last five UFC bouts, although his last appearance resulted in a split draw with Luan Chagas at UFC 198. “The Panther” is 5-1-1 in the promotion and 10-2 as a pro overall.
