Ugas, 36, previously held the WBA championship belt and last fought in April last year. Barrios, who holds the super lightweight belt, returned to the ring in February after a year-long hiatus.
The full champion of the World Boxing Council in this weight category is Errol Spence Jr., who has not boxed for almost a year, and is going to fight in the super welterweight limit next fight. Ugas is ranked second in the WBC rankings, and Barrios is fifth.
