Golden Boy Promotions President Oscar De La Hoya is very worried about Saul "Canelo" Alvarez's defense of the WBC 154-pound title, which takes place later tonight against former welterweight champion Kermit Cintron in Mexico City.

De La Hoya is nervous about Cintron's threat of being a dangerous puncher with his back against the wall. Should he lose tonight, Cintron will likely not receive another major televised showcase in the near future.

"I am very concerned with Cintron, because he knows it's his last chance to be at this level, and these type of fighters they train and prepare themselves to be at their utmost best to stop this train, the Canelo Express," De La Hoya told Sal Rodriguez.

"Canelo has to prove that he's a good champion in every fight. There are a lot of opponents out there for him, and he will face them in good time - like [Floyd] Mayweather, [Manny] Pacquiao, [Miguel] Cotto and [James] Kirkland."

Edison Reynoso, manager and coach of Canelo, is also concered with Cintron.

"He's a dangerous puncher. He has a lot of experience. He fought many fighters like [Alfredo] Angulo, Paul Williams, Sergio Martinez and Antonio Margarito. People will use this fight to compare Canelo to those fighters [who faced Cintron in the past]," Reynoso said.
