Numerous sources coming out of Indonesia have advised that WBA featherweight champion Chris John is unable to move forward with his June 27 rematch with Rocky Juarez. The fight, set for the Staples Center in California, was the HBO televised co-feature to Victor Ortiz-Marcos Maidana.

From what sources told BoxingScene, John was feeling ill and fatigued during some of his recent training sessions. After being evaluated by a physician, irregularities were discovered in his blood. Calls to John's team were not immediately returned. More information to come.
