UFC bantamweight Umar Nurmagomedov (20-2) will make his Real American Freestyle (RAF) debut against UFC Hall of Famer Urijah Faber (35-11 MMA) on November 14 at the Etihad Arena in Abu Dhabi, United Arab Emirates.
Nurmagomedov, a cousin of former UFC lightweight champion Khabib Nurmagomedov, has seven submission victories in MMA and will compete under freestyle wrestling rules against the former WEC featherweight champion.
Faber, 47, will make his third RAF appearance, having suffered technical fall defeats to Henry Cejudo and Arman Tsarukyan in his previous two outings.
The event will be headlined by Khamzat Chimaev and Colby Covington, who will contest the RAF Cruiserweight Crossover title.
Olympic gold medalist and reigning RAF light heavyweight champion Kyle Snyder will also defend his championship against Shamil Erdogan, an unbeaten MMA fighter with a freestyle wrestling background.
