Andy Foster, the executive director of the California State Athletic Commission (CSAC), has confirmed that Jon Jones' drug test has come back clean.
ESPN's Brett Okamoto tweeted that the United States Anti-Doping Agency and CSAC had tested the 31-year-old American on the night of UFC 232.
"No picograms of the M3 metabolite, which was the source of all the controversy and drama last month, were found," he added.
UFC president Dana White announced last month that UFC 232 would be moved from Las Vegas to California after Jones had not received a license from the Nevada State Athletic Commission.
The UFC fighter was able to obtain a license from the CSAC, as Foster told ESPN's Ariel Helwani that he had taken a surprise urine test and had passed that test.
It's unsurprising that Jones has welcomed the news, taking to his Instagram account to issue a statement.
"Finished my so-called kryptonite before the championship rounds," he wrote.

"Absolutely no jet fuel found @alexthemauler just wanted to make sure you saw this. Seemed like that was the only thing you could focus on in our last fight.
"Interested to hear the excuses of my next few victims. Only 51 more days to go, will you be a witness?"
Jones made his return at UFC 232 against Alexander Gustafsson and defeated him for the UFC Light Heavyweight Championship.
Cain Velasquez has recently expressed his desire to step into the octagon with Jones.
Who should Jones fight next?
