New details emerge regarding Brock Lesnar’s failed drug tests

Just two days before UFC 200, UFC pound for pound kingpin Jon Jones was pulled from his headlining bout with Daniel Cormier after being notified of a potential anti-doping violation.

In the days following UFC 200, it was reported that Jones failed the drug test for an estrogen blocker. The following weekend, it was revealed that Brock Lesnar had failed a random out-of-competition drug test back in June.

Tuesday morning, it was revealed that Lesnar had also failed a fight night drug test. While no details were immediately available regarding what Lesnar failed the drug tests for, news has now surfaced that the former heavyweight champ failed a drug test for the same estrogen blocker as Jon Jones did.

According to sources, Brock Lesnar tested positive for Clomiphene, the same anti-estrogen blocker Jon Jones tested positive for.
