Rapidly turning into a dominant fighter settling in for a long reign at the top, UFC flyweight champion Alexandre Pantoja returns home to Brazil on Saturday, May 4, to defend his crown for the second time against surging Australian contender Steve Erceg in the main event of UFC 301 at Farmasi Arena in Rio de Janeiro. Winner of five in a row, Pantoja has been a man on a mission, and after a 2023 campaign in which he won and defended his title against Brandon Moreno and Brandon Royval, he's back to meet Erceg, who is perfect in three trips to the Octagon. Plus, the King of Rio returns to the Octagon, as UFC Hall of Famer Jose Aldo makes the walk for the first time since 2022 to face Jonathan Martinez.
