Edgar Chairez takes Bruno Silva’s back, sinks in a first-round rear-naked choke at UFC Vegas 118

Edgar Chairez turned a competitive start into a decisive grappling finish, submitting Bruno Silva with a rear-naked choke at 4:13 of Round 1 in their flyweight bout at UFC Vegas 118 on June 6, 2026. According to the finish recap, Silva was left bloodied after absorbing damaging strikes, and Chairez closed the sequence by taking Silva’s back and choking him out rather than letting the moment slip away.

The way the fight unfolded mattered because it was not just a single takedown-to-finish path. Cageside Press described Silva repeatedly trying to work on the outside and then inside, landing a right hand and an uppercut, before Chairez responded with his own jab-heavy offense and a strike combination that briefly put Silva down. The pivotal shift came with a second knockdown, again stemming from uppercut and hook work, after which Chairez followed Silva to the mat and secured the rear-naked choke.

That finish style was echoed by the UFC highlight coverage Sherdog posted alongside the bout. The highlight write-up states Chairez hurt Silva on the feet before finishing with the rear-naked choke, framing it as a full-round statement that started with striking and ended with control. UFC’s own video listing for the matchup also describes Chairez submitting Silva in the opening round, aligning the timing with what other result trackers reported.

Chairez’s win built on recent momentum. Cageside Press reported that the submission was his third straight victory and his second submission finish within that run, a sign that his game plan was trending toward fights where he could do damage and then transition into submission opportunities quickly.

The bout took place inside UFC Apex in Las Vegas as part of UFC Fight Night: Muhammad vs Bonfim, the 12-bout event that Sherdog lists under UFC Fight Night 278. With the headliner going to Gabriel Bonfim, the undercard delivered its own version of title-picture pressure in the flyweight ranks by showcasing a finisher capable of ending fights early when he finds the right moment.

For the sport, the most immediate takeaway is stylistic. Chairez’s ability to hurt a longer opponent and then convert to back control reinforces why flyweight bouts can turn quickly from a standup exchange into a grappling closeout. What to watch next is whether the UFC books Chairez against another high-volume opponent who can challenge his takedown entries and scramble defense, and whether Silva rebounds with a more decisive answer to the kind of back-taking sequence that ended his night.

Silva, for his part, will likely need to recalibrate how he prevents the kind of late-round pressure Chairez applied after the second knockdown. Even without overreading the result into standings, a first-round rear-naked choke loss is the kind of defeat that can change matchmaking priorities, because it highlights how vulnerable a fighter can be once the fight turns from trading strikes to being forced into defensive scrambling and submission defense.
