Sonnen: Jon Jones failed UFC 200 drug test caused by estrogen blockers

Former two-time Ultimate Fighting Championship (UFC) Middleweight title contender, Chael Sonnen, claims to know the answer to the million-dollar question regarding what banned substance Jon Jones tested positive for that prompted the United States Anti-Doping agency (USADA) to pull him from UFC 200.

And during a recent appearance on "The Joe Rogan Experience" with UFC's Joe Rogan, Sonnen revealed the culprit.

"This doesn't make Jon innocent at all. Jon is guilty," Sonnen said. "The only card that he had to play is what did you test positive for, and they refused to reveal it. He tested positive for some estrogen blockers," claims Sonnen as transcribed by Fan Sided.

"He tested positive for two estrogen blockers, there I revealed it. Aren't we creating some news?"

Sonnen -- who is well-versed in the area given his numerous transgressions (details here and here) that ultimately led to pulling the curtain on his combat career -- says there seems to be a missing piece to the puzzle regarding the drama surrounding the former Light Heavyweight champion.

"Turns out it's a pretty good test," Sonnen said. "There's a reason this test is 40-plus grand. But, the thing I'm wondering is if Jon has another test out there. There's more to the story, that's the piece that is still missing."

According to Rogan, estrogen blockers are usually taken by someone who is cycling off performance enhancing drugs (PED's), specifically steroids.

"Estrogen blockers are usually when people are getting off of steroids," Rogan said. Sonnen then went on to confirm.

"Correct, when you're coming off of a cycle," said Sonnen. "Guys don't want estrogen so you take the blocker to block that. That's a way they can catch you after the fact."

Jones is adamant he didn't knowingly take any banned substance and declared during a press conference (see it) that he would never cheat in any way to gain a competitive advantage over his foes. But, until USADA or Jones and Co. reveal what he actually got popped for, it's all pure speculation as to what exactly he took.
