USADA: Jon Jones ‘B’ sample also comes back positive for banned substance
Esther Lin, MMA FightingUSADA said Friday in a statement that the ‘B' sample taken from Jones on June 16 also came back positive. The UFC interim light heavyweight champion was pulled from UFC 200 this week after he failed an out-of-competition drug test.
"I can confirm that Mr. Jones' B sample results have been reported by the laboratory, and that the results confirm the findings of the A sample," USADA spokesperson Ryan Madden said in a statement.
USADA will not confirm what substance or substances Jones tested for unless Jones or his team makes that information public first. UFC president Dana White said this week on FS1 that Jones popped for two separate banned agents.
