Barrios last fought in November on the undercard of the Netflix event headlined by Jake Paul vs. Mike Tyson. He fought Abel Ramos to a draw, allowing him to retain his WBC welterweight title.

Pacquiao, 46, will return to challenge WBC welterweight champion Mario Barrios in a PBC on Prime Video pay-per-view on July 19 in Las Vegas, according to a report from ESPN's Andreas Hale. The co-main event will reportedly include an anticipated rematch between Sebastian Fundora and Tim Tszyu for the WBC junior middleweight title.

Barrios retained his title in November after battling Abel Ramos to a draw in a bloody war on the undercard of the Jake Paul vs. Mike Tyson card. Barrios' other most notable fight came in June 2021 when he suffered a TKO loss to Gervonta "Tank" Davis in a very competitive bout.
