Panama's Luis "Nica" Concepcion has arrived in Hermosillo, Mexico and he's very focused on his rematch with WBA flyweight champion Hernan "Tyson" Marquez, which takes place on Saturday night at the the CUM Center. "Tyson" (31-2-0, 24 KOs) and "Nica" (23-2-0, 18 KOs) are ready to continue their war from April, when Marquez captured the title with an eleven round stoppage.

"I prepared a lot better this time, much better than I did for our first fight. This time Marquez will not be able to beat me. I'm going to show up on Saturday and shut a lot of mouths and regain my belt. All of the people in Panama are going to be watching this rematch with Tyson and we will not fail them," said Concepcion.
