Boxing's only eight-division world champion, Philippine Senator and regular WBA welterweight champion Manny "Pac Man" Pacquiao returns to face undefeated Super WBA Welterweight World Champion Keith "One Time" Thurman in a powerhouse 147-pound showdown live on Premier Boxing Champions on FOX Sports Pay-Per-View event on Saturday, July 20 at the MGM Grand Garden Arena in Las Vegas.

Preceding the pay-per-view is a FOX PBC Fight Night also taking place at MGM Grand that is headlined by undefeated IBF Super Middleweight World Champion Caleb "Sweet Hands'' Plant making his first title defense against unbeaten contender Mike Lee.

Possessing speed, power and tremendous boxing skills, Thurman represents the most dangerous challenger that the future Hall of Famer Pacquiao has faced in his recent ring appearances. This high-stakes match will firmly give the winner a claim for the top spot in one of boxing's deepest and most talented divisions.

Tickets for the event, which is promoted by MP Promotions, Mayweather Promotions and TGB Promotions, are on sale now and can be purchased online through AXS.com, charge by phone at 866-740-7711 or in person at any MGM Resorts International box office.

In his last match on January 19, Pacquiao put on a vintage performance against four-division champion Adrien Broner, scoring a 12-round unanimous decision in the 70th match of his illustrious career. It was his first time fighting in the U.S. in two years. Before that, he scored an impressive knockout over Lucas Matthysse to win his version of the WBA welterweight championship in Malaysia last July 15.

The 30-year-old Thurman (29-0, 22 KOs) is the longest reigning welterweight champion in boxing, having collected his WBA title with a stoppage victory over Diego Chaves in 2013. He has successfully defended that title eight times and became a unified welterweight champion when he defeated Danny Garcia by split decision to win the WBC title. Plagued by a litany of injuries, including bone chips in his right elbow that had to be surgically removed, Thurman was out of action for nearly two years before getting back into the ring with a hard fought victory against Josesito Lopez in January on FOX.

Having taken up the sport when he was in grade school, the Clearwater, Florida native blossomed under the tutelage of his first trainer, Ben Getty, to become an outstanding amateur. Though Getty has passed away, Thurman still carries those boxing and life lessons with him whenever he steps into the ring with his current longtime trainer Dan Birmingham. His power punching earned him the nickname "One Time.''

"I'm extremely excited for this opportunity to get a fight that I've wanted for a long time,'' said Thurman. "The right circumstances have aligned for it to happen now and I'm grateful for that. Me and my team are looking forward to it. It's going to be an honor to be in the ring with Manny Pacquiao. It's going to be fun to go back to MGM Grand in my first pay-per-view with FOX Sports. I believe that Ben Getty would be very proud of what I've been able to accomplish. He said I'd be able to dominate the welterweight division and be a multi-million-dollar fighter and a star in the sport.

"Manny Pacquiao is beatable. He's been beaten before in his career. He's a fan favorite and a legend. For me his boxing tactics are predictable. He fights in spurts and you have to take advantage of that. You have to be respectful of his power. But I believe my movement, athleticism and ring knowledge will be able to present him something he's not seen in all his years of boxing.''
