Following last weekend’s UFC 331 card, the UFC returns home to Las Vegas tonight for another UFC Fight Night event at the Meta APEX.

In the main event, surging bantamweights Raul Rosas Jr. and Raoni Barcelos will both try and extend their respective win streaks in a fight that features an age gap of nearly 20 years between the two men.

The co-main event will also be contested at 135 lbs., as Norma Dumont will try to kick off a new win streak when she takes on Ailín Pérez, who comes into the night following six-straight victories.

UFC Vegas 121 Main Card Includes The Ultimate Fighter 34 Finals

The men’s bantamweight finals feature highly-touted prospect Mahammadali Osmanli, who will square off with Kyrgyzstani standout Ilimbek Akylbek.

The main card is rounded out by a short-notice light heavyweight bout between Sedriques Dumas and Luis Hernandez, which will see Hernandez step in to make his promotional debut less than two weeks after earning a UFC contract on Dana White’s Contender Series.
