Well, this certainly changes things. A few weeks after Wanderlei Silva refused a drug test from the Nevada State Athletic Commission which led to his removal from UFC 175, reports have surfaced that his opponent, Chael Sonnen has failed his test in Nevada.
As a result of the failed drug test, Sonnen will no longer face his new opponent, Vitor Belfort, on July 5 at UFC 175.
The UFC has already commented on the situation.
“UFC officials acknowledge irregularities in a recent random test,” the UFC said. “Chael is planning on addressing the matter this afternoon.”
NSAC chairman Francisco Aguilar confirmed the test results to ESPN.com.
Sonnen reportedly tested positive for an anti-estrogenic. The two illegal substances in his system were reportedly Anastrozole and Clomiphene.
The three-time UFC title challenger has previously been on testosterone-replacement therapy, but the treatment has since been banned by a number of athletic commissions throughout the sport.
Sonnen previously tested positive for an elevated testosterone-to-epitestosterone ratio in August of 2010.
Sonnen is expected to address the situation at 6 p.m. ET on FOX Sports 1.
UFC 175 is headlined by a middleweight title fight between current champion Chris Weidman and challenger Lyoto Machida. A women’s bantamweight title fight between Ronda Rousey and Alexis Davis will serve as the co-main event.
