UFC middleweight Josh Samman ’s death has been ruled a probable drug overdose. The Broward County (Fla.) Medical Examiner’s office issued the official cause of death today after an autopsy on Samman’s friend showed he died of a “massive” accidental drug overdose. Broward County’s Chief Medical Examiner Craig Mallak confirmed the news to MMAjunkie after an initial report from TMZ . Samman’s friend, Troy Kirkingburg, had heroin, cocaine, Xanax, and ethanol (or alcohol) in his system when he died, the autopsy revealed. Mallak told TMZ he determined the cause of death because he was found with Kirkingburg and tested positive for drugs at the hospital he was rushed to after police were called on a suspected drug overdose. Samman came to the UFC courtesy of “The Ultimate Fighter 17,” where he fought under Jon Jones.
