The 2026 UIJJ Bologna BJJ Challenge is set to feature a highly anticipated matchup between American grappler Chris DeMari and Italian veteran Thomas Campanella, scheduled for June 12, 2026, at the BolognaFiere exhibition center in Bologna, Italy. The event, organized by the United International Jiu-Jitsu Federation (UIJJ), will showcase elite-level Brazilian Jiu-Jitsu competition across multiple weight classes, with the DeMari-Campanella bout drawing particular attention due to their contrasting styles and recent form on the international circuit.
Chris DeMari, a 28-year-old black belt from San Diego, California, has emerged as one of the most promising no-gi specialists in the lightweight division. A former collegiate wrestler at Arizona State University, DeMari transitioned to BJJ full-time in 2020 and quickly rose through the ranks with a pressure-based passing game and aggressive leg attack series. His most recent notable performance came at the 2025 ADCC West Coast Trials, where he secured a submission win over former IBJJF world champion Mikey Musumeci in the semifinals before falling in the final. DeMari holds a brown belt in judo and is affiliated with the Atos Jiu-Jitsu headquarters in San Diego.
Thomas Campanella, 34, represents the experienced European contingent in the UIJJ rankings. A native of Naples, Italy, Campanella earned his black belt under legendary coach Fabio Gurgel in 2018 and has since become a consistent podium finisher in European IBJJF and UAEJJF events. Known for his tight half-guard game and exceptional defensive resilience, Campanella recently captured gold at the 2025 European IBJJF Championship in the lightweight division, defeating reigning champion João Gabriel in the final via points. He trains regularly with the Checkmat team out of Rome and has competed in over 150 international matches since 2019.
Their head-to-head history remains limited, with only one prior encounter recorded: a 2023 UAEJJF Abu Dhabi World Pro qualifier match where Campanella won by advantage after a scoreless regulation period. That bout took place in the gi, whereas the upcoming Bologna challenge will be contested in no-gi rules under UIJJ format — a potential advantage for DeMari, whose wrestling base and explosive transitions thrive in faster-paced, submission-oriented rule sets.
UIJJ events follow a modified double-elimination bracket system with match durations set at eight minutes for quarterfinals and semifinals, extending to ten minutes for the final. Overtime consists of a three-minute sudden-victory period, followed by referee decision if no submission occurs. Points are awarded for takedowns (2), sweeps (2), guard passes (3), knee-on-belly (2), and mount/back control (4), with advantages given for near-submissions or near-point-scoring actions. Competitors are weighed in the morning of competition with a 0.5kg allowance permitted.
BolognaFiere, located in the heart of Emilia-Romagna, has hosted major combat sports events including UFC Fight Night gatherings and European judo championships. The venue’s Hall 29, where the BJJ challenge will take place, offers approximately 12,000 square meters of space with regulated temperature control and elevated seating for up to 8,000 spectators. Local organizers expect significant turnout from the Italian grappling community, with free admission for youth athletes under 16 and discounted tickets available through regional sports associations.
From a tactical standpoint, DeMari’s path to victory likely hinges on imposing his wrestling pressure early to disrupt Campanella’s guard retention. His ability to chain takedowns into immediate leg entanglements — particularly the inside heel hook and knee bar — has proven effective against guard-oriented opponents in recent no-gi outings. Campanella, meanwhile, will aim to slow the pace, invite DeMari into his half-guard, and sweep or transition to back exposure when the American overcommits on passing attempts. His recent success against pressure passers relies on framing, hip escape timing, and counter-attacks from the turtle position.
Injury reports released by both athletes’ camps indicate full availability. DeMari completed a recent training camp in Brazil with no reported setbacks, whereas Campanella confirmed via his Instagram story on June 5 that he had cleared all medical checks and felt “strong and loose” ahead of travel to Italy. Neither athlete appears on the UIJJ’s official medical suspension list as of June 10.
The winner of this match advances to the quarterfinals of the lightweight division bracket, where they would face either the victor of the Gabriel Sousa vs. Lucas Pinheiro match or receive a bye depending on bracket placement. A win for DeMari would mark his first major international no-gi victory over a top-five ranked European opponent, potentially elevating him into contention for a 2026 ADCC World Championship invitation. For Campanella, a win would represent his first significant victory over a U.S.-based elite no-gi specialist and solidify his status as a gatekeeper in the European lightweight scene.
As the global BJJ calendar continues to expand, events like the UIJJ Bologna Challenge serve as critical evaluation points for athletes aiming to qualify for year-end championships such as the ADCC World Championships and IBJJF No-Gi World Cup. With live coverage planned through UFC Fight Pass and select regional broadcasters, the bout will be accessible to international audiences starting at 6:00 PM local time in Bologna (12:00 PM UTC).
Fans looking to follow the action can access real-time results and bracket updates via the official UIJJ website, which will begin publishing match-by-match coverage one hour prior to the first scheduled bout. Post-event analysis and highlight reels are expected to be archived on the federation’s YouTube channel within 24 hours of the competition’s conclusion.
