At Pride Shockwave 2003, Sakuraba would face Antônio Rogério Nogueira, brother to the famous Antônio Rodrigo Nogueira. The Brazilian, having promised to knock out the Japanese, opened the match lunging at him with punches, but Kazushi answered in kind and opened a cut on Nogueira's eye which almost stopped the bout. The action resumed, both men battled for several minutes, with Rogério gaining the upper hand in striking and Sakuraba in wrestling, allowing him to get in Nogueira's guard and inflict significant damage again. During the second round, Nogueira managed to catch Sakuraba in a triangle choke/armbar combo, but the Japanese escaped the hold and sought his own submission, to no effect. Finally, the third round saw Nogueira taking over with punches and knees, exchanging strikes with Sakuraba almost until the last minute, and ultimately winning the decision.
