Rosas Jr. faces UFC Hall of Famer Clay Guida in RAF debut at Chicago's NOW Arena

Raul Rosas Jr. will step outside the UFC octagon once more, meeting retired veteran Clay Guida at RAF 15 on November 28 at NOW Arena in Chicago. The promotion confirmed the matchup on Friday, adding a marquee bout to a card that already features former UFC champions Anthony Pettis and Donald Cerrone.

Still only 22, Rosas has built one of the most remarkable early careers in MMA history. He became the youngest fighter ever signed through Dana White’s Contender Series at 17, and then the youngest to win a UFC bout when he defeated Jay Perrin on debut. He has since rattled off six consecutive UFC bantamweight victories, most recently finishing Raoni Barcelos at UFC Vegas 121.

RAF 15 will be Rosas’ fifth combat sports appearance of 2026 alone. Alongside two UFC wins this year, he fought to a draw with former UFC flyweight champion Deiveson Figueiredo at a Hype FC event and submitted Khasan Magomedsharipov in the first round at an ACBJJ event in July.

Guida, 44, brings a storied but winding road to this matchup. The veteran retired from MMA in 2024 after more than 60 professional bouts, 37 of which came inside the UFC. He was inducted into the UFC Hall of Fame’s Fight Wing in 2019 for his all-action clash with Diego Sanchez at The Ultimate Fighter 9 Finale — a bout widely regarded as one of the promotion’s most entertaining fights.

In RAF specifically, Guida has yet to taste victory, going 0-3 against Frankie Edgar, Keelon Jimison, and Cayden Henschel. He will need to end that skid against one of the sport’s most hyped young talents.

The Pettis vs. Cerrone clash adds further star power to RAF 15, reuniting two fan favourites whose UFC careers defined an era of lightweight competition.
