While both men did indeed make weight, Dumas clocked in at just 197 pounds. How the weight difference will play a role in the fight will be something to keep your eyes on.<\/p>\n<p>Headliners Raul Rosas Jr. and Raoni Barcelos were also clean on the scale. Rosas used the one-pound allowance for a non-title fight, while Barcelos\u2019 weight was 135 pounds on the nose.<\/p>\n<p>The entire weigh-ins pretty much went down without a hitch, but there was one exception that ultimately worked out. Preliminary fighter John Castaneda couldn\u2019t reach the 136-pound limit on his first attempt for a bantamweight tilt against Alateng Heili. Castaneda hit his target on his second try.<\/p>\n<p>Here are the full UFC Vegas 121 weigh-in results:<\/p>\n<p><strong>Main Card (Paramount+, 8 p.m. ET)<\/strong><\/p>\n<ul>\n<li>Raul Rosas Jr. (136) vs. Raoni Barcelos (135)<\/li>\n<li>Norma Dumont (136) vs. Ailin Perez (136)<\/li>\n<li>Luis Hernandez (204) vs. Sedriques Dumas (197)<\/li>\n<li>Mehemmedeli Osmanli (136) vs. Ilimbek Akylbeck Uulu (135.5)<\/li>\n<li>Melissa Amaya (116) vs. Tina Black (116)<\/li>\n<\/ul>\n<p><strong>Prelims (Paramount+, 5 p.m. ET)<\/strong><\/p>\n<ul>\n<li>Brady Hiestand (135.5) vs. Rinya Nakamura (136)<\/li>\n<li>Rodolfo Vieira (186) vs. Robert Bryczek (185.5)<\/li>\n<li>Rodolfo Bellato (204.5) vs. Christian Edwards (205)<\/li>\n<li>Elves Brener (155) vs. Josiah Harrell (155.5)<\/li>\n<li>Montel Jackson (136) vs. Ricky Simon (135.5)<\/li>\n<li>John Castaneda (136) vs. Alateng Heili (136)<\/li>\n<li>Vanessa Demopoulos (116) vs. Yazmin Jauregui (115)<\/li>\n<\/ul>\n<p>Fresh off the biggest win of his career to date against Rob Font, Rosas is hoping to nab his sixth straight victory. Barcelos is riding a five-fight winning streak himself, and the 39-year-old is making the most of his career before the window shuts. Time will tell if it\u2019s youth or experience that wins the night in Las Vegas.<\/p>\n<p><strong>What are your final predictions for UFC Vegas 121?
