The UFC’s return to Rio de Janeiro, Brazil for a UFC Fight Night event on October 11 is nearly at full capacity following a new batch of bout announcements.

Headlined by former UFC Lightweight Champion Charles Oliveira and top-ranked lightweight contender Rafael Fiziev, UFC Rio added a number of fights last week when the promotion confirmed Deiveson Figueiredo vs. Montel Jackson and three other matchups.

The UFC matchmakers have clearly been busy, as UFC Rio has officially gotten an additional four fights to give the October 11 event 13 total bouts.

Gabriel Bonfim vs. Randy Brown

In one of two newly-announced bouts to include a ranked fighter, Gabriel Bonfim will look to distance himself from a contentious win over two-time UFC title challenger Stephen “Wonderboy” Thompson when he takes on Randy Brown.

“Rude Boy” is coming off a knockout-win over Nicholas Dalby that earned him a “Performance of the Night” bonus, and at UFC Rio he’ll have a chance to jump back into the welterweight Top 15 against the #14-ranked Bonfim.

Valter Walker vs. Mohammed Usman

Also sitting at #14 in the UFC heavyweight division, Valter Walker is currently on an incredible three-fight winning streak that has seen him finish all three opponents via heel hook in the first round.

It only took “The Clean Monster” 54 seconds to dispatch Kennedy Nzechukwu in his last outing, but Mohammed Usman will also enter UFC Rio with a bit of confidence after he handed Hamdy Abdelwahab the first loss of his professional MMA career and snapped a two-fight skid in the process.

Other Additions To UFC Fight Night Rio

Although not quite as high-profile as Bonfim vs. Brown and Walker vs. Usman, UFC Rio also added a pair of intriguing featherweight and lightweight bouts to round out the card.

Longtime UFC veteran Ricardo Ramos could well be fighting for his job in Rio after going 1-3 in his last four outings, although his opponent Kaan Ofli has also had a tough go of things in the Octagon after reaching the finals of The Ultimate Fighter Season 32.

Michael Aswell will attempt to secure his first UFC victory when he meets Lucas Almeida, who hopes to even out his promotional record after going 2-3 since his 2022 debut. With the addition of four new fights roughly a month and a half before the event, UFC Rio currently looks like this:
