Brendson Ribeiro used his victory at UFC Vegas 122 to ask for help finding his missing brother in Brazil.Ribeiro snapped a four-fight losing streak on the Fight Night card this past weekend by submitting Felipe Franco in the first round of their light heavyweight bout.Ribeiro locked in a guillotine to finish Franco inside two minutes and earn his first UFC win in 19 monthsGettyIt was the first time the Brazilian light heavyweight had tasted victory since March 2025 and the 30-year-old was overcome with emotion afterwards.Members of the media quickly found out exactly why Ribeiro was so upset despite winning when he explained his brother has been missing for almost six months.Ribeiro makes plea over missing brother“We don’t think that he’s alive anymore,” Ribeiro told reporters through an interpreter during his post-fight press conference, per MMA Junkie.“We just want to understand. Give us some closure on this. Help us. Whether it’s his remains.View Tweet: https://x.com/hashtag/UFCVegas122?src=hash&ref_src=twsrc%5Etfw“My dad is suffering. The wife is suffering. The brothers are suffering.“I just want to make sure people understand we need some closure and some information and hopefully end this nightmare that’s haunting the entire family.”Ribeiro: My family has no voice in BrazilRibeiro said his brother went missing in the northern Brazilian state of Para on April 27, just a month after his daughter was born.“He is my blood brother from my dad’s side,” he added.“The authorities have not said anything. My family has no voice there. “As an athlete that has a platform right now, I just want to get it out there for someone to help us.Ribeiro was overcome with emotion when celebrating his victory on the Fight Night card in Las VegasGetty“Whether it’s the governor or the mayor or the authorities, just to help us understand what happened.”Ribeiro admitted it was understandably incredibly tough to prepare for his Las Vegas fight, which he took on two weeks’ notice, with the added weight of his brother’s situation on his shoulders.However, he now believes he’s entering a new chapter of his career and his victory was ‘the work of 15 years culminating’ in one night.“I think this is another re-debut, another debut in the UFC, the Chute Box representative, 18-11 in his professional career, said.“The biggest mistake people make is to underestimate me and to count me out. I’m not saying [Franco] did that, but a lot of people don’t believe in me and believe I could do this.“I’ve had so many finishes and a lot of guillotines. This is another guillotine for the belt.”talkSPORT's UFC pound-for-pound rankingstalkSPORT.com has collectively voted on the best fighters to form a regularly updated UFC pound-for-pound (P4P) rankings system for the rest of 2026 and beyond.Our P4P list will be updated regularly based on performances in the Octagon — with wins, records, title wins and defences, calibre of opponents, methods of victory and much more all determining who makes it.UFC champions Islam Makhachev, Joshua Van and Sean Strickland feature – but big stars such as Alex Pereira and Tom Aspinall miss out.
