The B sample from Jon Jones' failed drug test before his light heavyweight title fight at UFC 214 confirmed the presence of an illegal substance, sources told ESPN's Brett Okamoto.

Jones had been flagged by the USADA for testing positive for an anabolic steroid called Turinabol after defeating Daniel Cormier for the title. He faces a four-year suspension and loss of his title due to the positive test.

Jones has denied knowingly taking steroids and his team says it is investigating how the positive test happened, but the failed B sample likely means that any reasoning that is found won't stop a USADA suspension.

The result of the UFC 214 main event has yet to be modified, though it will likely be changed to a no contest and Cormier will be returned the light heavyweight title. The UFC can only strip Jones of the title, while the USADA can levy a suspension.

Jones passed a blood test, though the substance in question is not detectable through that means of investigation.
