Charles Oliveira will defend the BMF title against Diego Lopes in the UFC 335 main event Dec. 12 at T-Mobile Arena in Las Vegas, the promotion announced Saturday.
In the co-headliner, former two-division champion Alex Pereira will make his second heavyweight appearance against Sergei Pavlovich. It will be a five-round bout.
Additionally, Joe Pyfer and Bo Nickal will square off in a pivotal middleweight clash.
Oliveira, a former lightweight champion, captured the BMF belt with a unanimous decision win over Max Holloway at UFC 326 in March. The 36-year-old Brazilian is riding a two-fight winning streak.
Lopes, a former two-time featherweight title challenger, is making his debut in the UFC lightweight division. The 31-year-old Brazilian is coming off a TKO win over Steve Garcia at the White House in June.
Pereira, the former light heavyweight and middleweight champion, moved up to heavyweight earlier this year in an attempt to become the first three-division champ in UFC history. However, he suffered a TKO loss to Ciryl Gane in an interim title bout at UFC Freedom 250.
The 39-year-old Brazilian defended the 205-pound belt three times across two reigns.
Pavlovich is the No. 2-ranked contender in the heavyweight division. He's riding a three-fight winning streak, most recently beating Tallison Teixeira by TKO in 39 seconds in May.
