Rosas Jr. and all 24 fighters clear the scale ahead of UFC Vegas 121

All 24 fighters on the UFC Vegas 121 card successfully made weight on Friday at the UFC Apex in Las Vegas, setting up a generational contrast in the main event between rising bantamweight Raul Rosas Jr. and seasoned Brazilian contender Raoni Barcelos.

Rosas Jr. (12-1) stepped on the scale at 136 pounds — one pound above the non-title bantamweight limit — for what will be his first UFC main event. The 21-year-old Californian is riding momentum from the biggest win of his career, a decision victory over Rob Font, and a second consecutive high-profile scalp would push him firmly into contender territory.

Barring his way is Barcelos (22-5), who weighed in at exactly 135 pounds. The 39-year-old Brazilian brings 18 years of experience to the cage and arrives in the form of his career, having strung together five consecutive victories over notable opponents including Ricky Simon, Cody Garbrandt, Payton Talbott, and Montel Jackson.

The age gap between the two headliners — 18 years — frames the fight as a classic experience-versus-youth matchup, with Rosas Jr. looking to prove his precocious talent can overcome a battle-hardened veteran at the peak of his powers.

Elsewhere on the card, former featherweight contender Norma Dumont and Ailin Perez both came in at 136 pounds for their women’s featherweight bout, while the light heavyweight co-main event between Luis Hernandez (204) and Sedriques Dumas (197) is set after both men cleared the 205-pound limit.
