“Showtime” just received a considerable upgrade in competition.

Newly crowned Real American Freestyle (RAF) Middleweight Crossover champion Arman Tsarukyan will defend his title against former Ultimate Fighting Championship (UFC) Lightweight champion Anthony Pettis in the RAF 15 main event on Sat., Nov. 28, 2026, inside NOW Arena in Chicago, Illinois.

The event will stream exclusively on FOX Nation.

Tsarukyan competed less than one week ago at RAF 14, where he completely shut out Dillon Danis to capture the inaugural Middleweight Crossover title. The UFC Lightweight contender scored a dominant 10-0 technical fall before stepping on Danis’ body and celebrating his latest piece of hardware (watch highlights).

The 30-year-old has quickly become one of RAF’s biggest crossover stars and recently revealed that he plans to collect victories over as many recognizable mixed martial arts (MMA) fighters as possible.

Pettis certainly fits that description.

“Showtime” captured the UFC Lightweight championship with a first-round submission over Benson Henderson in 2013 and also held gold under the World Extreme Cagefighting (WEC) banner. While best known for his creative striking, Pettis also recorded eight submissions during his 36-fight MMA career.

Pettis was originally scheduled to make his RAF debut against longtime rival Donald Cerrone at RAF 15. The two former UFC stars were expected to meet for the third time after Pettis defeated “Cowboy” in both of their previous Octagon encounters.

Instead, Pettis will receive a much more difficult wrestling assignment against RAF’s newest champion.

RAF 15 will also feature Henry Cejudo defending his Lightweight Crossover championship against Song Yadong, Raul Rosas Jr. facing UFC Hall of Famer Clay Guida, and former Bellator champion Sergio Pettis wrestling former UFC Bantamweight kingpin Cody Garbrandt.
