Akiyama's gloves were found to be regulation, video-tape revealed Akiyama administering a lotion to his skin. Akiyama—who attested he was simply treating his dry skin—was found to have been "negligent" and disqualified. The fight was subsequently declared a no-contest and Akiyama's purse was withheld. A press conference followed, wherein Akiyama—now heavily maligned by the Japanese sports media—offered a public apology. Although Sakuraba wore a shirt into the ring against Akiyama which read "K Sakuraba: End of Service", his experience against Akiyama apparently changed his plans regarding retirement and at Heros 8 he submitted the winless Yurij Kiseliov by armbar.
