Two welterweight fights have been added to UFC Fight Night 100 in Sao Paulo, Brazil, on Nov. 19.

Three days after scoring his first UFC win, Zak Ottow already has his next fight lined up, as the promotion announces him as Sergio Moraes’ new opponent in Sao Paulo. Ottow replaces Mike Graves, who got pulled from the fight after being arrested for domestic violence.

Ottow (14-3) enters the bout coming off five straight victories, capped off by a split decision win over long-time veteran Josh Burkman in his Octagon debut last Saturday in Portland. The 29-year-old welterweight scored 10 of his 14 wins by way of submission.

Moraes (10-2-1) is undefeated as a welterweight in the UFC, but looks to go back to the win column following a split draw against Luan Chagas at UFC 198. Prior to his most recent fight, the jiu-jitsu ace went 4-0 with here finishes.

The second bout officially announced by the promotion features Warlley Alves and Kamaru Usman.

Alves (10-1) was one of the top prospects out of Brazil until he fought Bryan Barberena at UFC 198 in May. A huge favorite in the fight, Alves lost via unanimous decision in Curitiba, snapping a four-fight winning streak under the UFC banner.

Another welterweight talent to enter the promotion through its reality show The Ultimate Fighter, Usman (8-1) is unbeaten in the Octagon after a submission victory over Hayder Hassan and a pair of decisions against Leon Edwards and Alexander Yakovlev.

UFC Fight Night 100 takes place at Sao Paulo’s Ibirapuera gymnasium and features a rematch between Antonio Rogerio Nogueira and Ryan Bader in the main event.
