The scheduled World Boxing Council super bantamweight title match between Oscar "Chololo" Larios of Mexico and Japan's Kozo Ishii, originally scheduled to take place Aug. 10 in Nagoya, will be put off until early September as Ishii suffered an injury during training, boxing sources said Friday.

According to the sources, the fight at Aichi Martial Arts Gymnasium in Nagoya will probably take place either Sept. 7 or 14 as the seventh-ranked Japanese challenger hurt his back muscles in training.
