At 46, Pacquiao is older than George Foreman when Foreman defeated Michael Moorer to win the IBF and WBA heavyweight titles in 1994. Pacquiao also hasn't fought professionally in just shy of four years, retiring after being beaten by Yordenis Ugas in August 2021. That Ugas fight came more than two years after Pacquiao's previous bout.

A full Saturday of boxing is on tap for July 19 in Las Vegas, when welterweight champion Mario Barrios and Manny Pacquiao square off in a main event.

Manny Pacquiao returns to the boxing ring for the first time in four years on Saturday to face Mario Barrios. The 46-year-old Pacquiao is understandably an underdog given his lack of recent time in the ring. WBC welterweight champion Barrios is 16 years younger than his opponent and has fought five more times than him over the last four years.
