CSAC on Jon Jones’ positive VADA test: ‘There’s no evidence of re-administration’

California State Athletic Commission director Andy Foster speaks further about Jon Jones’ positive WADA test after UFC 232.

Jon Jones’ UFC 232 post-fight drug-test conducted by the Voluntary Anti-Doping Association (VADA) came out positive. The current light heavyweight champion, however, will receive no punishment from the California State Athletic Commission or the UFC.

According to CSAC executive director Andy Foster, they found “no grounds” to punish Jones for the exact same reason, especially after consulting with some scientists who were overseeing the matter.

The non-sanctioning of Jones had raised some eyebrows, considering his past failures. But in another interview with James Lynch of, Foster shed more light on the issue, stating no evidence of re-administration of the drug in question was found.

“The scientists have said there was no evidence of re-administration, the evidence… when we go back and look at the testing from August until now,” Foster said. “It is indisputable that there’s been no re-administration and there’s no way to prove re-administration between July and what I believe is August of 2018, so Jon Jones, like any athlete, is afforded the presumption of innocence.

“That doesn’t change based on who you are, he served his time,” he continued. “He sat out his time and scientists say – multiple scientists have said, including the expert scientists that I used when I got Jon for the metabolite in 2017, put in writing that there’s no evidence of re-administration.”

After reclaiming the title with a win over Alexander Gustafsson, Jones is now slated for his first title defense as new champion against Anthony Smith at UFC 235 on March 2nd in Las Vegas.
