World champion Yurikoris Gamboa, who usually trains in Miami, is off to the Fight Factory in Tampa, Fla. He is preparing to take on champion Orlando Salido of Mexico on Top Rank’s ‘Battle of the Champions’ on September 11 at the Palms Resort Casino, Las Vegas. Gamboa, 18-0, usually trains in Miami. “It’s a big fight and we wanted to get away and do it right,” said chief trainer Tony Gonzalez. It’s the same training facility used previously by world champion Miguel Cotto. Gamboa is the WBA featherweight champion. Salido is the IBF champion. Team Gamboa is planning to report to Las Vegas on Friday, Sept. 3.

Unbeaten Russian middleweight Matt Korobov is on the ‘Battle of the Champions’ fight card at the Palms. He is training with Kenny Adams in Las Vegas. Korobov, 11-0, is scheduled for eight rounds.
