Mayweather-Berto undercard all set

Mayweather Promotions has announced that two undercard fights will be taking place on the now-official Mayweather-Berto PPV. In one of the televised undercard fights, WBO Junior lightweight titlist Roman "Rocky" Martinez (29-2-2, 17 KOs) will be once again taking on Orlando Salido (42-13-2, 29 KOs) in a rematch of their April slugfest - a tough fight that had Martinez getting the decision after dropping Salido a couple of times. Salido didn't help his own cause either that night, with his patented low-straying blows earning him a late point deduction. But it was a fight of the year candidate, so let's do it again!

"We are ready and working hard to make sure this title remains in Puerto Rico," Martinez said. "Everyone saw the first fight against Orlando Salido, and I know that this second bout will also be a war. Once again we have the rivalry between Puerto Rico and Mexico, which guarantees plenty of action."

Salido, who should be on the receiving end of most of the cheers on Mexican Independence Day weekend, is also eager for the rematch. He says he got off to a slow start and had to fight both Martinez and the referee that night, but on this night he fully expects to knockout Martinez.

The other title fight will be super middleweight Badou Jack (19-1-1, 12 KOs) making his mandatory title defense against George Groves (21-2, 16 KOs). Jack won the WBC title by beating Anthony Dirrell in April.

"I'm very excited, and I'm preparing for the toughest fight of my career against George Groves," Jack said. "I always go into a fight with an underdog mentality, even as champion. It feels great to be defending in my adopted hometown of Las Vegas. My promoter, Floyd Mayweather, has had my back during the ups and downs of my career, and I want to make him and the whole Mayweather Promotions team proud on Sept. 12."

George Groves is now coming into this fight off two consecutive wins, after experiencing two consecutive knockouts at the hands of Carl Froch, "in front of 80,000 screaming fans at Wembley Stadium," I think the story goes.

"Badou Jack isn't 'bad' enough to halt my dream," he said. "His WBC belt is all that is on my mind each and every waking moment. We have studied Jack. We are prepared for his strengths and ready to expose his weaknesses. Vegas is my second home, and I can't wait to come back with a bang."

Lastly, as a special bonus, Ishe Smith (27-7,12 KOs) will take on Vanes Martirosyan (35-2-1, 21 KOs) on regular ol' Showtime prior to the start of the PPV telecast.
