On the night of UFC 214, Jon Jones passed a blood test administered by USADA, according to MMAFighting’s Ariel Helwani. The post-fight blood test was taken after Jones defeated Daniel Cormier to win the UFC Light Heavyweight Championship.
MMAJunkie reached out to USADA, who have confirmed that Turinabol is screened by WADA using a urine test. This is likely why the drug would not turn up in Jones’ blood test the next day.
This was a day after Jones took a pre-fight urine test that flagged positive for the steroid Turinabol.
