This is the live blog for Raul Rosas Jr. vs. Raoni Barcelos, the bantamweight main event for Saturday’s UFC Vegas 121 fight card at the Meta APEX in Las Vegas.

Rosas Jr., the youngest athlete in UFC history to earn a contract when he got a victory on Contender Series at just 17 years of age, competes in his first octagon main event. Now 21, Rosas enters the bout on a five-fight win streak, including a decision victory against Rob Font at UFC 326 in March. “El Niña Problema” is 6-1 overall in the UFC with the lone loss coming to Christian Rodriguez at UFC 287 in April 2023.

Barcelos is also entering his first UFC main event on a five-fight win streak, including handing Payton Talbott his lone octagon defeat. The 39-year-old’s impressive run also includes wins over Montel Jackson, Ricky Simon and former champion Cody Garbrandt.

Well, that co-main event was so bad that Paul Felder just kinda went after Ailin Perez over it.

Hopefully this main event will be better.

Chito Vera in Raul Rosas’ corner. That’s a fun wrinkle. Both men looking ready. Barcelos looking like a weathered old man who will beat the heck out of any upstart young whippersnappers. Let’s see if he can do just that to Rosas.

Oh, the screen tells us that this is the largest age gap in a UFC fight ever, at 17 years. That’s something interesting!
