Guan Wang will be looking to extend the 11-0-1 record that marks him as one of the best pound-for-pound fighters in China, when he takes on Brazilian Sandro Da Silva (3-2). Their rematch will headline RUFF 10 on Aug. 24 in Shanghai. The event, which is set for the Hongkou Indoor Stadium, also sees the return of Zhang Meixuan and Rodrigo Caporal, who, like Wang, were crowned inaugural RUFF superfight champions in February. Meixuan (5-1) won the flyweight strap and will be returning to action to take on Ya Fei (1-1). Lightweight title winner Rodrigo Caporal (9-4) has won five fights out of five for RUFF and will be looking to continue this winning streak when he goes up against Russian wrestler Rasul Khairulaev (1-0).
