WNO 31: Pena vs. Griffith full card lineup and preview
Here is everything you need to know about WNO 31: Pena vs. Griffith, which takes place on Friday, December 5, 2025.
A trio of title belts will be on the line this Friday evening when FloGrappling’s Who’s Number One (WNO) returns to action in Round Rock, Texas.
The card has undergone a significant number of changes. A lightweight title bout between Diego “Pato” Oliveira and Deandre Corbe was scrapped just two days prior to the event. Also, a hotly anticipated clash between Andy Murasaki and Dante Leon was postponed, and decorated veteran Xande Ribeiro received a new opponent.
In the main event, familiar foes Felipe Pena and Luke Griffith will square off for the vacant WNO heavyweight crown. Before that, pound-for-pound star Helena Crevar will put her featherweight belt on the line against veteran black belt Julia Boscher.
Felipe Pena vs. Luke Griffith
The evening’s headlining attraction will see Pena and Griffith each look to stake their claim as the sport’s top heavyweight competitors.
Pena is one of the most accomplished athletes in the history of grappling. With notable career wins over the likes of Gordon Ryan, Nick Rodriguez, and Marcus “Buchecha” Almeida, he’s firmly solidified himself among the all-time greats. And although he’s 34 years old and seemingly in the twilight of his career, he hasn’t lost a step against the best competition available, having claimed his second ADCC world title just a little over a year ago.
For his part, Griffith has spent the past few years evolving from one of the sport’s top prospects to a bona fide elite talent. After a disappointing first-round exit at ADCC 2022, the Kingsway product bounced back two years later to capture silver at ADCC 2024. He would subsequently score an impressive win over Victor Hugo to secure himself a crack at WNO gold.
Notably, this will be the third meeting between these two heavyweight juggernauts. The pair first collided in the final of the +99kg division at ADCC 2024, where Pena employed his veteran savvy and world-class back-taking game to weather an early storm to ultimately secure a rear-naked choke finish.
They met one year later at CJI 2. Pena dominated the entirety of the match before locking in an armbar finish, but it’s worth noting that Griffith had just competed in a match against Diego “Pato” Oliveira, while Pena came into the contest fresh and rested.
The third match between Pena and Griffith promises an interesting clash of styles. While both athletes are dangerous from any position, Pena does his best work attacking from his guard and looking for the back, while Griffith is an excellent takedown artist and guard passer who will employ pressure to expose the back.
Helena Crevar vs. Julia Boscher
Young phenom Helena Crevar looks to be the sport’s top pound-for-pound competitor at the moment, and she’ll come into her featherweight title defense as a significant favorite against Julia Boscher.
Still just 18 years old, Crevar employs an aggressive closed guard game and dangerous leg locks that complement her ever-evolving pressure passing. After earning silver at the 2024 ADCC World Championships, she firmly established herself as a pound-for-pound powerhouse when she defeated Adele Fornarino and Sarah Galvao to win the six-figure prize at CJI 2. Outside of a 90-second decision loss at Polaris Squads, the Kingsway product hasn’t tasted defeat in no-gi competition in well over a year.
Boscher, meanwhile, will be looking for a breakout win. A black belt since 2019, the 30-year-old’s biggest and best accomplishments have come in the gi, where she is a Brasileiros absolute champion.
The rest of the card at WNO 31
Elsewhere on the card, Xande Ribeiro will continue his late-stage comeback tour when he takes on 2024 IBJJF no-gi world champion Faris Benlamkadem, who represents a serious challenge for the veteran fan-favorite.
Also, super-heavyweight standout Gabi Pessanha will square off with Paige Ivette Clymer. Pessanha has been practically unstoppable over the past few years, absolutely dominating the IBJJF circuit in both gi and no-gi action, but Clymer, with her elite athleticism and ample experience in no-gi competition, poses a real threat to upset the Brazilian star.
Finally, a late-notice match between leg lock experts Chris Wojcik and Oliver Taza promises plenty of action in a cross-town clash between Simple Man Martial Arts and Kingsway.
