UFC Vegas 121 Recap: Raul Rosas Jr. Survives War With Raoni Barcelos in Frightening Fifth-Round Finish

By Brian Hradsky
MSB Fight Club

Raul Rosas Jr. entered Saturday night looking for the biggest victory of his young career and left the Meta APEX in Las Vegas with his sixth consecutive win, but the celebration quickly became secondary after a frightening conclusion to his main event against Raoni Barcelos. Rosas defeated Barcelos by fifth-round TKO at 1:38 Saturday night, Sept. 26, after Barcelos suddenly lost consciousness during a grappling exchange and required immediate medical attention.

The 21-year-old Rosas improved to 13-1 and completed a dramatic comeback after Barcelos gave him serious problems throughout the first four rounds. Barcelos was removed from the Octagon on a stretcher and transported to a Level 1 trauma center, temporarily shifting the focus away from one of the most entertaining fights on the card. The UFC later reported that Barcelos was stable, alert and responsive with full movement after undergoing a CT scan and comprehensive evaluation.

That encouraging update was the most important development following a night filled with finishes and controversy. UFC Vegas 121 also saw Ailin Perez defeat Norma Dumont in a heated co-main event, Luis Hernandez remain undefeated with a 57-second submission, Ilimbek Akylbek win The Ultimate Fighter 34 bantamweight tournament through disqualification and Tina Black capture the women’s strawweight TUF crown.

Rosas and Barcelos Deliver a Main-Event War

Rosas entered his first UFC main event as one of the promotion’s most intriguing young fighters, but Barcelos represented a significant step up in experience. The veteran Brazilian refused to allow Rosas to simply impose his grappling game and repeatedly answered the younger fighter’s aggression with effective striking. What developed was considerably more competitive than a showcase for the rising bantamweight contender.

Rosas pushed a furious pace early and showed improvement in his striking, but that aggression also created openings. Barcelos found those openings and repeatedly connected while Rosas continued moving forward. The fight became increasingly physical as both men accumulated damage and fatigue through the middle rounds.

By the championship rounds, Rosas was badly marked up, including a significant cut across the bridge of his nose. Barcelos had also absorbed substantial punishment, but neither fighter appeared interested in slowing the pace enough to coast to the scorecards. Four rounds of exchanges left both men exhausted heading into the fifth.

Then everything changed.

Frightening Ending in the Fifth

Rosas closed distance early in Round 5 and engaged Barcelos along the fence. During the grappling exchange, Rosas used a leg sweep to bring Barcelos toward the canvas. Barcelos suddenly became unresponsive during the sequence, prompting the fight to be stopped at 1:38 of the fifth round.

The exact mechanism that caused Barcelos to lose consciousness was not immediately clear from the available replays. Reports noted that he may have made contact with the fence during the takedown sequence, but the replay did not definitively establish what happened. Rosas recognized that something was wrong and signaled for the referee as medical personnel entered the cage.

Barcelos was immobilized and taken from the Octagon on a stretcher before being transported for evaluation. His coach, Davi Ramos, subsequently reported that Barcelos had regained his senses, while the UFC’s medical update said the Brazilian was stable, alert and responsive and had full movement after his evaluation.

The official result remains a fifth-round TKO victory for Rosas. It moved his professional record to 13-1 and extended his winning streak to six fights.

Rosas Continues Rapid Rise

Rosas has lived under an unusual amount of attention since becoming the youngest fighter ever signed to the UFC following his appearance on Dana White’s Contender Series. Saturday represented another major stage in his development because he was asked to fight five rounds against an experienced veteran rather than overwhelm an opponent in a short grappling exchange.

The performance was not flawless, and Barcelos demonstrated that Rosas can still be hit when he becomes overly aggressive. However, Rosas showed that he could continue competing deep into a demanding fight after encountering adversity. His willingness to engage on the feet also showed a more diversified offensive approach than the grappling-heavy style associated with his early UFC appearances.

The victory should further establish Rosas in the bantamweight picture. The UFC listed him as its No. 12-ranked bantamweight entering the event, meaning his next opponent could carry even greater divisional significance.

Perez Defeats Dumont in Heated Co-Main Event

Ailin Perez defeated Norma Dumont by unanimous decision in a women’s bantamweight grudge match that remained heated after the final horn. All three judges scored the fight 29-28 for Perez, improving her record to 14-2.

Perez established herself in the opening round by winning much of the striking battle before securing a late takedown. Dumont increased her aggression in the second and scored an early takedown of her own, although Perez quickly worked back to her feet. Dumont connected with one of the round’s most significant punches late in the period as the rivalry became increasingly personal.

Perez used clinch work against the fence during the third round and landed a hard knee to Dumont’s body. She also connected with a left hand near the horn before tensions boiled over. Security personnel entered and separated the fighters, preventing the confrontation from continuing after the fight had officially ended.

The unanimous 29-28 decision surprised Dumont, who appeared confident she had done enough to win. Perez celebrated afterward, which nearly sparked another confrontation. Whatever happens next, their rivalry clearly did not end simply because the judges turned in their scorecards.

Luis Hernandez Needs Only 57 Seconds

Luis Hernandez produced one of the night’s fastest performances against Sedriques Dumas. Hernandez secured a standing guillotine and forced the submission only 57 seconds into the first round.

Hernandez improved to 9-0 with the victory and did not allow Dumas enough time to establish any sustained offense. Once Hernandez locked the choke, Dumas was caught in a position from which he could not recover. It was the type of dominant short performance that can quickly raise a fighter’s profile.

The circumstances surrounding the matchup were unusual because Hernandez entered significantly heavier than Dumas following a short-notice situation. Hernandez nevertheless capitalized immediately once the cage door closed.

Illegal Knee Decides TUF 34 Bantamweight Final

The Ultimate Fighter 34 bantamweight final ended in one of the night’s strangest and most disappointing moments. Ilimbek Akylbek defeated Mehemmedeli Osmanli by disqualification at 2:19 of the opening round after Osmanli delivered an illegal knee to the head of his grounded opponent.

Akylbek had already secured a takedown and established control before the illegal strike. Osmanli then landed the knee while Akylbek remained grounded, and the impact appeared to render Akylbek unconscious. Referee Kerry Hatley ultimately stopped the contest and awarded Akylbek the disqualification victory.

The victory gave Akylbek the TUF 34 bantamweight tournament championship and extended his winning streak to three. Osmanli’s nine-fight winning streak ended with the disqualification.

Tina Black Captures TUF Strawweight Crown

Tina Black defeated Melissa Amaya by second-round TKO to capture the TUF 34 women’s strawweight tournament championship. Black stopped Amaya with punches at 3:19 of Round 2, improving her professional record to 17-4.

Unlike the bantamweight finale immediately following it, Black’s victory left no controversy surrounding the result. She steadily broke Amaya down before producing the finishing sequence in the second round. Amaya entered the fight with a 9-0 record but suffered the first professional defeat of her career.

Prelims Produce Several Big Finishes

The preliminary card featured plenty of action before the main card even began. Yazmin Jauregui needed only 62 seconds to knock out Vanessa Demopoulos with punches in the opening fight, immediately setting an aggressive tone for the night. Jauregui improved to 12-2 while Demopoulos dropped to 11-9.

Alatengheili followed with a split-decision victory over John Castaneda. Two judges scored the fight 29-28 for Alatengheili while the third gave Castaneda the same score. Montel Jackson then delivered one of the preliminary card’s most significant finishes when he knocked out Ricky Simon at 2:39 of Round 2.

Elves Brener stopped Josiah Harrell with strikes at 4:14 of the opening round, while Christian Edwards scored a third-round TKO against Rodolfo Bellato at 1:47. Rodolfo Vieira provided one of the few decision victories on the preliminary card, sweeping Robert Bryczek 30-27 on all three judges’ scorecards.

Brady Hiestand closed the preliminaries with an upset submission against Rinya Nakamura. Hiestand secured a rear-naked choke at 4:07 of Round 2, handing Nakamura another setback while improving his own record to 10-2.

MSB Fight Club Take

The lasting image from UFC Vegas 121 will unfortunately be the frightening conclusion of Rosas-Barcelos, but the fight before that moment deserves recognition. Barcelos forced Rosas into the deepest and arguably most difficult test of his UFC career. Rosas could not simply depend on an early takedown and submission; he had to absorb punishment, manage exhaustion and continue fighting into the fifth round against a veteran who refused to go away.

Rosas remains remarkably young for someone already competing against ranked UFC bantamweights. There are still obvious areas for him to improve, particularly defensively when he becomes aggressive with his striking, but surviving a fight like this could become an important part of his development. His next matchup should tell us even more about whether he is ready to move from intriguing prospect into legitimate bantamweight contention.

The biggest news after the event, however, is that Barcelos was reported stable, alert and responsive after the frightening ending. Fight results become secondary when a fighter leaves the cage on a stretcher, and the positive medical update provided some relief after an unsettling conclusion to an otherwise action-packed UFC Fight Night.

UFC Vegas 121 ultimately delivered almost every possible type of MMA result: knockouts, submissions, decisions, an upset, a disqualification, a heated rivalry and a five-round main-event battle. For MSB Fight Club, Rosas’ victory is the headline, but Barcelos’ health remains the most important story coming out of Las Vegas.
