Five Major Positive Drug Tests in MMA


Stephan Bonnar post Anderson

The first ever Ultimate Fighter grand final match between Stephan Bonnar and Forrest Griffin was so memorable that it widely seen as being responsible for the explosion of MMA’s popularity.

Since then the man known as the American Psycho enjoyed a solid career in the UFC, having gone 8-6 in seven years with the organisation. His final MMA fight was at UFC 153 against one of the top pound-for-pound fighters at that time, Anderson Silva, who temporarily moved up to light heavyweight to help save the injury-plagued event.

Bonnar lost the fight in the first round, something that shocked few, if any fans and critics of the sport. What was shocking was the fact that Bonnar tested positive for Drostanolone (an anabolic steroid) in the post-fight drug test.

It was not the first time Bonnar tested positive for banned substances – he tested positive for Boldenone after the Forrest Griffin rematch in 2006. However, the second positive test seemed to mark the end of Bonnar’s career as evidence by his subsequent retirement from the sport.

It didn’t fully ruin his reputation, however, as he was officially inducted into the UFC Hall of Fame in July 2013.

From Perth, Australia, Bruno has been an MMA fan on and off (mostly on) for 10 years. He did Taekwondo for a few years as a kid and dabbled in BJJ and Muay Thai as an adult, but is more an MMA fan than anything else. He is also an experienced journalist and writer, having written a number of articles on an array of topics.
