the skin over Sakuraba's left eye, which Ricardo then capitalized on by squeezing the cut and digging his finger into it in order to force the doctor stoppage. The Japanese tried to keep on, but Arona hit another flurry of knees to the head, and ended the fight landing soccer kick after soccer kick, rendering Kazushi's face severely swollen and bloody.

The bout was a competitive one, with Sakuraba choosing to fight from the bottom and using both men's submission attempts to force scrambles. After long minutes pinned under Sakuraba, Minowa escaped and took his
