The matchup, officially announced Wednesday, will headline the event, with Cejudo’s RAF lightweight crossover championship on the line.
Cejudo, an Olympic wrestling gold medalist, had previously expressed interest in a rematch with Song. He will now have the opportunity to avenge his defeat under freestyle wrestling rules rather than inside the Octagon.
Following their first encounter, Cejudo competed once more in the UFC, suffering a decision loss to Payton Talbott. He has since transitioned to RAF, facing former UFC bantamweight champion Urijah Faber and current UFC star Merab Dvalishvili.
In his most recent wrestling appearance, Cejudo defeated Dvalishvili in their second meeting to capture the RAF lightweight crossover title, which he will defend against Song.
Song, meanwhile, has continued his success in the UFC, recording consecutive main-event victories over former flyweight champion Deiveson Figueiredo and Umar Nurmagomedov. The Chinese bantamweight will make his RAF debut against Cejudo.
The November 28 event will also feature several recognizable MMA veterans, including Donald Cerrone against Anthony Pettis, Clay Guida against Raul Rosas Jr., and Cody Garbrandt against Sergio Pettis.
