Chael Sonnen fails drug test

  • Chael Sonnen announced his retirement from MMA competition after he failed a drug test issued by a Nevada State Athletic Commission. 

    "I want to take an opportunity to officially announce my retirement from competitive mixed martial arts," he said. "I had a great time."

    The 37-year-old was tested positive for two substances last month, but he mentioned that the results indicated his intake of fertility medication. However, he has taken responsibility for the results this time around.
