According to a report on Japanese site Sportsnavi, the venue for the May 26th bout between WBC Flyweight Champion Daisuke Naito and Chinese challenger Xiong Zhao Zhong has been moved from Shanghai to Tokyo on less than a week's notice due to vague "problems which cannot be cleared." This certainly takes some of the shine off the fight - Zhong is the first Chinese boxer to challenge for a world title, and it would have been nice for him to fight in front of his countrymen. Now he's just an outmatched challenger trying to take the belt on the champ's home turf.
