Chael Sonnen, who retired from MMA just weeks ago after failing a random drug test for multiple banned substances, failed a second random drug test that was administered by the Nevada State Athletic Commission, according to MMA Fighting.
Sonnen, who announced his retirement earlier this month, was asked to take a second drug test following his initial failure, as he was set to be licensed to compete at the upcoming UFC 175 show on July 5. Sonnen tested positive for both HGH (human growth hormone) and EPO (recombinant human erthopoietin), both illegal substances. These substances were in addition to HCG (human chorionic gonadotophin_ and anastrozole, in which he also tested positive for during his first test.
The test was administered one week before Sonnen announced his retirement from MMA. Both Sonnen and the UFC found out about the test failure earlier this week.
Sonnen was set to face rival Wanderlei Silva at UFC 175 on July 5, before Silva refused to take a mandatory drug test and was replaced by Vitor Belfort, pending a license approval. However, word of Sonnen’s first drug test failure scrapped all three fighters from the card altogether.
Sonnen told MMA Fighting the following:
“Yes, the Commission is aware of other prescribed medications I was taking and I will not challenge their allegations. I will cooperate with the Commission and look forward to having a dialogue about how fighters who transition off TRT can avoid violating any rules.”
Sonnen will appear before the NAC on July 23 to discuss the matter of both drug test failures.
