YOKOHAMA, Japan - Ginjiro Shigeoka has undergone brain surgery after collapsing in the ring following his loss to Pedro Taduran on Saturday.
Shigeoka was fighting Taduran for the second time, after he lost his IBF flyweight title to him last July. Shigeoka was beaten badly and also collapsed in the ring after their first encounter, but was given the all-clear ahead of the rematch.
