The market has Franco at 73% (-340/+250), and the recent-form evidence backs that up. The stats block flags Franco as a UFC debutant, but that is a stale database entry: his form log shows two UFC bouts, a decision loss to Mario Pinto (March 2026) and a punches stoppage of Levi Rodrigues Jr. (July 2026). So I don't apply the 65 cap, but I still treat his 1-1 UFC record as a thin sample. Ribeiro has lost four straight. He absorbs more than he lands (2.94 vs 3.56 significant strikes per minute), lands only 40% of his strikes and stops only 32% of takedowns. He has three first-round KO/TKO losses (Zhang, Murzakanov, Sy) and was choked out by Yakhyaev. He is also a replacement for Alexander Poppeck, 77 days after his last fight. The notice date is undocumented, so that is only a small adjustment against him. Franco has an 11-2 record and leans toward grappling, so he can finish with his hands or by taking down someone with weak takedown defense. Ribeiro's live paths are a kimura in a scramble or using his 81-inch reach to win on points, and his recent results make both unlikely. I sit slightly under the market because Franco's UFC sample is small and the Pinto loss shows a durable opponent can take him to a decision.

Franco starts as the 74% market favorite, but his explicit UFC-debut flag conflicts with the supplied record and makes his statistical averages unreliable; confidence is capped at 65%. Ribeiro's four consecutive losses include two knockout defeats and one submission, supporting vulnerability across finishing routes. Franco's reported recent knockout win supports the stoppage pick, although opposition quality is insufficiently established. Ribeiro's short-notice replacement status reinforces the lean but likely already factors into the market. Both fought recently, so extended layoff risk is absent. Method percentages are conditional on a Franco win.
