Each axis comes from a measured career average, scaled to a fixed 0–100 range.
Fight confirmed for UFC Fight Night / UFC Vegas 121, on September 26, 2026, at the Meta APEX in Las Vegas, in the bantamweight division, over 5 rounds of 5 minutes. Rosas is coming off a decision victory over Rob Font on March 7, 2026; Barcelos is coming off a split-decision victory over Montel Jackson on April 25, 2026.
Barcelos has 15 UFC fights compared with 7 for Rosas and more bouts against ranked opponents, according to the comparison consulted; however, this secondary source does not officially measure the individual quality of the opponents.
No previous matchup between Raul Rosas Jr. and Raoni Barcelos is recorded in the comparison consulted. There is therefore no direct reference point for assessing their actual interaction; the conclusions are based on their separate profiles and on career samples of secondary quality.
No public injury affecting either fighter is confirmed in the sources consulted. This does not constitute proof that there is no injury.
Their medical status, any potential difficulty with weight cutting, and physical condition on the day of the weigh-in are unknown.
Across 7 UFC fights, Rosas averages approximately 6.8 takedowns per 15 minutes, 54% success, and approximately 8.5 minutes of control time per 15 minutes. Across 15 UFC fights, Barcelos averages approximately 4.65 significant strikes attempted per minute, 51% accuracy, 61% striking défense, and 88% takedown défense; 74% of his recorded significant strikes are standing strikes versus 19% on the ground.
Rosas scenario: he closes the distance, repeatedly attempts takedowns, and controls enough to win by decision or submission. Barcelos scenario: he defends the initial entries, punishes exits, and keeps the fight standing; experience and volume could then weigh more heavily.
Advanced production data show a decline for Rosas and an increase for Barcelos in rounds 2 and 3, but the samples become smaller in the later rounds. Neither has demonstrated UFC experience here over five rounds.
The UFC matchup is confirmed, with Raul Rosas Jr. facing Raoni Barcelos. The fight is scheduled for 5 rounds of 5 minutes.
No confirmed opponent replacement was found. The official weigh-in has not yet taken place; the actual weight reached and the final continuation of the format remain to be verified.
Raul Rosas Jr. presents a clear path through takedowns, control against the cage, and a decision, while Raoni Barcelos can reverse the dynamic with his takedown défense, long-range striking, and greater UFC experience.
