Here's when to expect Manny Pacquiao and Mario Barrios to walk out to the ring for their WBC welterweight title fight in Las Vegas.

Pacquiao's pay-per-view fights have generated nearly $1.3 billion in revenue, including a staggering $400 million for his highly publicized 2015 fight against Mayweather. That fight also represented Pacquiao's highest payday to date, with him bringing in an estimated $130 million from the bout.
