BoxingScene.com was informed by promoter Lou DiBella that Celestino Caballero is "ready, willing and able" to replace the injured Elio Rojas on September 11 in Las Vegas.

Rojas, the WBC featherweight champion, was scheduled to fight WBA champion Yuriorkis Gamboa in an HBO televised unification bout. BoxingScene was informed by several reliable sources on Monday that Rojas suffered a shoulder injury in training camp and was likely out of the fight. Rojas is scheduled to have an MRI on Tuesday.

"Caballero is ready and willing to stop Gamboa's unbeaten streak. Caballero will fight anyone. Gamboa can't say he's the best featherweight in boxing if he won't fight Caballero," DiBella said.
