MGM Grand, Las Vegas - Leonard Ellerbe, CEO of Mayweather Promotions, says WBC/WBA welterweight champion Floyd Mayweather Jr. (46-0, 26KOs) is focused on scoring a knockout victory in his rematch with Marcos Maidana on Saturday night. Mayweather had a tougher time than expected in May, when he walked away with a twelve round majority decision win over Maidana. This time he wants to close the show with a knockout, says Ellerbe.

"Maidana is a tremendous fighter. He's been an underdog for a number of years. Floyd has very openly taken on the challenge because the fans demanded the rematch. He said 'no problem, go ahead and put him in there.' He didn't cry or complain and say 'well, how about this other guy.' He said 'put his ass right back in there and if the fans don't think I got it done right the first time, I'll show them the next and my goal is to stop him this time.' So there will no questions left regarding the Mayweather-Maidana rematch," Ellerbe said.
