Mexican challenger Edgar Sosa, and the absolute flyweight champion of the World Boxing Council (WBC), Japan's Akira Yaegashi, went face to face during their mutual visit to the Japan Boxing Commission, where they passed the rigorous medical examinations on pace to their title fight this coming Friday at the Ryogoku Kokugikan arena in Tokyo, Japan. Sosa (49-7, 29 KOs), who in the past completed eleven defenses of the WBC junior flyweight world title, has been chasing his second divisional championship and plans to stun Japan by unseating Yaegashi (18-3, 9 KOs).
