Rosas Jr. Headlines UFC Vegas 121 Against Barcelos

Raul Rosas Jr. will headline his first UFC card against Raoni Barcelos at UFC Vegas 121 on Sept. 26.

The promotion announced the five-round bantamweight matchup over the weekend, per MMA Mania. The 21-year-old Rosas Jr. enters on a five-fight win streak, though his last three victories over Aoriqileng, Vince Morales, and Rob Font all came via decision after he started his Octagon run with three straight finishes. Rosas Jr. became the youngest fighter to sign a UFC contract at 17 through Dana White's Contender Series, then set another record as the youngest to win inside the cage when he submitted Jay Perrin at 18 years and two months old.

Barcelos Earns First Main Event After Late-Career Surge

Barcelos enters his first UFC headliner after 15 promotional appearances, riding a five-fight winning streak that includes victories over Payton Talbott, former bantamweight champion Cody Garbrandt, Ricky Simon, and Montel Jackson. The Brazilian veteran had dropped four of five fights three years ago, including a knockout loss to Umar Nurmagomedov, before turning his career around with the current run.

The card at Meta Apex in Las Vegas also features Norma Dumont versus Ailin Perez and the TUF 34 bantamweight and women's strawweight finals. Rosas Jr. still aims to become the youngest champion in UFC history, though Barcelos presents the toughest test of his young career.
