Background
On February 6, 2023, Jorge Masvidal announced on The MMA Hour that Roy Jones Jr. would face former UFC Lightweight champion Anthony Pettis in a professional boxing match on April 1, 2023. Masvidal also announced on the co-main event that former UFC Light Heavyweight champion Vitor Belfort would be facing former Strikeforce Middleweight champion Ronaldo "Jacare" Souza. The pair previously fought under the MMA rules set at UFC 198, where Souza won via TKO in the first round. The card also featured UFC Hall of Famer José Aldo take on fellow MMA veteran Jeremy Stephens. The pair also previously fought in MMA at UFC on Fox: Alvarez vs. Poirier 2 where Aldo would win the fight via TKO by body shot in the first round.

The event was originally planned to have a bout between former UFC and Bellator title contender Paul Daley and Anthony Taylor.
