Golden Boy Promotions CEO Richard Schaefer has officially announced that a deal has been finalized for WBC/WBA junior welterweight champion Danny Garcia (26-0, 16KOs) to defend his titles against mandatory challenger Lucas Matthysse (34-2, 32KOs) on the Floyd Mayweather Jr. vs. Saul Alvarez Showtime pay-per-view on September 14th at the MGM Grand in Las Vegas.

"The One just got even bigger. Floyd wanted to make the biggest pay-per-view possible," Schaefer said. "We didn't have to make this fight. The tickets are already sold out. We want to give a big thank you to the fight fans. This is the most expensive fight ever to get put on as [co-feature] on a pay-per-view. This is one of the most anticipated fights in the sport. It would have been much easier to put this on a separate date and more lucrative for us as a promoter, but this was done for the fans."

There will be a multi-city press tour to promote Garcia-Matthysse, which is going to include stops in New York City, Puerto Rico and Los Angeles. There will be an announcement next week on the press tour dates.

Both fighters are represented by powerful adviser Al Haymon.
