At PRIDE 28, Yokoi faced Heath Herring, but he was soon overwhelmed with a right hook and multiple knees, including illegal strikes to the back to the head that granted Herring a warning. He eventually lost the fight by TKO in the same way. Yokoi looked to make up for his defeat at the next event by taking on Mario Sperry, Brazilian jiu-jitsu world champion and Nogueira's trainer, but after an uneventful round of clinch striking Yokoi was again downed and hit with knees and soccer kicks for the TKO.
