Stephan Bonnar, The Ultimate Fighter Season One finalists tested positive for a band substance after the UFC 62 fight with Forest Griffin. According to the Nevada State Athletic Commission, Bonnar tested positive for the banned substance Boldenone, a banned anabolic chemical commonly used by veterinarians to treat injured horses. The NASC has given Bonnar 20 days to respond to the complaint. The NASC will then rule on the issue and impose a fine or even a suspension. I guess Bonnar was getting desperate given his string of recent losses.
