Jon Jones has tested positive for steroids in his UFC 214 victory over Daniel Cormier ... TMZ Sports has learned.
Our sources tell us ... Jones tested positive for Turinabol -- an anabolic steroid.
Jones won the July 29 fight -- taking the UFC light heavyweight belt from Cormier with a savage head kick followed by a barrage of punishing punches to Cormier's head.
The title now goes back to Cormier.
It's the second time Jones has failed a USADA drug test. He tested positive for banned substances in 2016 before UFC 200 and was pulled from the main event. Jones got socked with a 1 year ban.
We're told this time around, he could be banned for up to 4 years.
Jones had blamed his previous failed test on a male enhancement pill. He claimed he didn't realize the pill contained a banned substance and insisted he was NOT trying to gain a competitive edge.
If the test results hold up, it's unclear how he'll explain his way out of this one.
