How to track the 2026 November UFC Fight Night São Paulo fixtures
Charles Oliveira's lightweight resurgence and new Brazilian hydration testing enforcement shape the upcoming UFC São Paulo event. Fighters must navigate strict weight rules, such as the 15 percent threshold used by commissions to prevent excessive dehydration.
Oliveira’s lightweight status
Charles Oliveira remains a centerpiece of the lightweight division following his successful comeback. He won the vacant lightweight belt at UFC 262 by completing a reversal against Michael Chandler in the second round within 17 seconds. Oliveira later defended this title against Dustin Poirier at UFC 269. He also defeated Justin Gaethje with a first-round submission at UFC 274. These wins followed a period where he vacated the title after weighing 0.5 pounds over the 155-pound limit. His history in Brazil includes a fight against Kevin Lee in March 2020 and a lightweight matchup against Mateusz Gamrot in Rio de Janeiro. Charles Oliveira secured redemption by defeating former interim lightweight champion Justin Gaethje with a first-round submission after weighing 0.5 pounds over the 155-pound limit at the UFC 274 event. This trajectory defines his current standing. Other Brazilian stars like Thiago Santos have also seen major results in Sao Paulo, such as his knockout of Jack Hermansson with just one second remaining in the first round.
Hydration and weight enforcement
The enforcement of hydration testing and weight rules changes how fighters approach the scale in Brazil. Commissions like the California State Athletic Commission monitor weight fluctuations to prevent excessive dehydration. Athletes must stay within a 15 percent threshold of their official weigh-in weight to avoid scrutiny.
| Metric/Event | Specific Value/Limit |
|---|---|
| CSAC Weight Gain Threshold | 15 percent |
| Oliveira Weight Violation | 0.5 pounds over 155 |
| Topuria Weight Gain | 16 percent |
| Costa Weight Gain | 16 percent |
| ONE Hydration Test Timing | 3 hours before event |
Fighters frequently struggle to meet these strict requirements. Ilia Topuria showed a 16 percent increase, moving from 144.5 to 167.2 pounds after his fight against Alexander Volkanovski. Paulo Costa recorded a 16 percent increase, moving from 185.5 to 215.2 pounds. Other fighters like Ian Garry saw only a 6 percent increase, moving from 170.5 to 180.6 pounds after the official weigh-ins. Henry Cejdu recorded a 12 percent increase, moving from 135 to 150.6 pounds. Merab Dvalishvili’s weight increased by 16 percent, climbing from 135 to 156.8 pounds. Carlos Vera moved from 135.5 to 158.6 pounds, a 17 percent increase. Danny Barlow recorded a 16 percent increase, moving from 171 to 197.8 pounds. This enforcement targets the practice of dehydrating to hit a predetermined weight. ONE Championship uses similar protocols, requiring daily weight checks and urine specific gravity tests. Athletes must pass these specific gravity hydration tests three hours before the event. If an athlete fails a test, the commission disqualifies them from the event. Will the Brazilian commission implement even stricter daily checks like ONE Championship?
Tracking the Sao Paulo fixtures
Tracking the 2026 Sao Paulo fixtures requires looking at historical fight times and broadcast providers. The 2023 Sao Paulo event had prelims at 6 p.m. ET and the main card at 9 p.m. ET. That card included a heavyweight bout between Jailton Almeida and Derrick Lewis. The 155-pound division included Ismael Bonfim against Vinc Pichel and Elves Brener against Esteban Ribovics. Other weight classes included 170-pound fights between Gabriel Bonfim and Nicolas Dalby, and 185-pound bouts with Caio Borralho against Abus Magomedov and Armen Petrosyan against Rodolfo Vieira. Smaller weight classes like flyweight had Jafel Filho against Clayton Carpenter and 135-pound matchups like Victor Hugo against Daniel Marcos. Women’s strawweight competitors like Livia Renata Souza and Alex Chambers also appeared on earlier cards. You should check ESPN or ESPN+ for the latest schedule updates. The most reliable way to track these Sao Paulo fixtures is through official broadcast schedules and historical fight data. Historical records from the 2018 Sao Paulo card list Alex Oliveira against Carlo Pedersoli Jr. in the welterweight division. The 2018 card also had Thiago Santos against Eryk Anders in the light heavyweight division. For those following Renan Barao or Antonio Rogerio Nogueira, historical cards in Sao Paulo provide a baseline for expected talent.
