opponent for the June 2 K-1 Dynamite!! USA event in Los Angeles would be Japanese fighter Kazushi Sakuraba. Gracie defeated Sakuraba by a unanimous decision. However, a post-fight drug screen revealed that Royce had traces of Nandrolone in his system. "Use of steroids is simply cheating," said Armando Garcia, California State Athletic Commission executive director. "It won't be tolerated in this state." Steroids scandal On June 14, 2007, the California State Athletic Commission declared that Gracie had tested positive for Nandrolone, an anabolic steroid, after his fight with Sakuraba. According to the California State Athletic Commission, the average person could produce about 2 ng/ml of Nandrolone, while an athlete following "rigorous physical exercise" could have a level of around 6 ng/ml. Both "A" and "B" test samples provided by Gracie "had a level of over 50 ng/ml and we were informed that the level itself was so elevated that it would not register on the laboratory's calibrator," said the CSAC. Gracie was fined $2,500 (the maximum penalty the commission can impose) and suspended for the remainder of his license, which ended on May 30, 2008. Gracie paid the fine.

This was widely disputed by experts. According to ESPN, "In the former contest, he weighed in at 175 pounds; for Sakuraba, he was 188. One may not need to be nutritionist to observe that a muscle gain of 13 pounds in one year at the age of 40 is a strikingly accomplished feat. Athletes nearing the half-century mark are often happy to maintain functional mass, let alone pack it on".

His manager stated that they were actively negotiating with the UFC for a return to the Octagon and said it was just a matter of "getting it nailed down" and that there was plenty of time for it. On November 15, 2013, at UFC 167 on the 20th Anniversary of the UFC, Royce Gracie confirmed to MMA journalist Ariel Helwani that he had retired from competing in mixed martial arts.
