He came very close to finishing Cathal Pendred numerous times at UFC Fight Night: Dublin, but not only was Mike King not able to win his bout, he also failed his drug test. The TUF vet tested positive for an anabolic steroid in Nandrolone, and as punishment, he forfeits his $50,000 bonus and has been subsequently released from the promotion.
"The consequences for my conduct are truly significant," King said in a statement to MMA Fighting. "The life changing $50,000 Fight of The Night bonus I was awarded has been taken away, I have been informed that my UFC promotional agreement is being terminated, I have been placed on a nine month suspension, and I have publicly humiliated myself. I accept full responsibility for my actions and decisions and make no excuses."
His opponent, Pendred also reacted to the news via twitter as he campaigned to get the other half of the FOTN bonus, saying "P.E.D = Pendred Enjoying Dollars."
Nandrolone is a performance enhancing drug that promotes muscle growth, bone density, and red blood cell production. Other notable fighters who have tested positive on the banned substance throughout the years include Josh Barnett, Stephan Bonnar, Nate Marquardt, Royce Gracie, and Sean Sherk
