The IBF world flyweight title unification bout between interim champion Ginjiro Shigeoka and Mexican champion Daniel Valladares scheduled for Aug. 11 has been postponed after the Japanese boxer sustained a foot injury, the fight's organizer said Thursday.

Shigeoka became interim champion in April with a ninth-round knockout of the Philippines' Rene Mark Cuarto, which came three months after his title bout with Valladares was declared a no-contest due to an accidental head butt in the third round.

Due to his injury, Shigeoka has not trained since last weekend on the advice of his doctor. A source close to the matter said the bout is likely to be pushed back to October.

"I feel really sorry about it. I'll focus on recovering from my injury to get back in the ring as soon as possible," Shigeoka said through his gym.

Shigeoka has a 9-0 record with seven knockouts and one no-contest, while Valladares is 26-3-1 with 15 KO wins and one no-contest.
