Initially there were some doubts as to whether Sakuraba would be able to make it into the next round of the Hero's tournament based on the severity of the damage he endured against Smirnovas. However, Sakuraba reported that a follow-up CAT scan had found no irregularities and was then slated to face one-time Olympic judoka, Yoshihiro Akiyama in the tournament's semi-finals on October 9 in what K-1 hoped would be a high revenue match-up. The winner of that bout was to face the victor between Melvin Manhoef and Shungo Oyama to determine a tournament champion. However, during a hard sparring session for the upcoming bout Sakuraba began vomiting and fainted. After being rushed to the hospital he was diagnosed with vertebrobasilar damage that restricted blood circulation to the head and neck area. The doctors determined the damage was caused from years of untreated head injuries dating back to his college years.
