Jon Jones' 'B' sample also tests positive for banned substance, per USADA

After a report from ESPN's SportsCenter, USADA confirmed Jones' 'B' sample tested positive for the same banned substances his original 'A' sample did.

Former UFC light heavyweight champion Jon Jones was flagged for a potential violation of USADA's anti-doping policy on Wednesday night and subsequently pulled from his UFC 200 matchup against champ Daniel Cormier.

The following day, an emotional Jones addressed his removal from the landmark card at a press conference on Thursday. He denied knowingly using a banned substance and his manager, Malki Kawa, claimed it was very possible the failed drug test was because of a tainted supplement.

As requested by Jones' team, his 'B' sample was sent to the same WADA-accredited laboratory in Salt Lake City, Utah that tested his 'A' sample, in the off chance it would come back negative.

But Jones is out of luck.

"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, however, will not confirm the substance(s) Jones tested positive for in the June 16 out-of-competition drug test, until Jones or his team does. UFC president Dana White stated that Jones popped for a pair of "agents" in an interview on FOX Sports 1's The Herd earlier this week.

Jones, who was replaced by ex-middleweight titleholder Anderson Silva at UFC 200, is facing up to a two-year suspension from USADA, as well as punishment from the Nevada State Athletic Commission (NSAC).

UFC 200 takes place live from the T-Mobile Arena in Las Vegas on Saturday, July 9 and is headlined by Miesha Tate vs. Amanda Nunes for the women's bantamweight belt.
