Bonnar and Dave Herman
both failed their drug tests at UFC
Bonnar tested positive for the anabolic steroid Drostanolone, while
Herman was flagged for marijuana metabolites. MMAJunkie.com first
reported the development, and Sherdog.com confirmed the results
with Marc Ratner,
UFC vice president of regulatory affairs, who also verified
that all 24 fighters on the UFC 153 bill were tested for both
performance enhancing drugs and drugs of abuse. As Brazil does not
possess an athletic commission, the UFC once again acted as its own
regulatory body at UFC 153. Fighter suspensions have not yet been
UFC 153 took place Oct. 13 at the HSBC Arena in Rio de Janeiro and
was headlined by Bonnar’s light heavyweight duel with longtime
middleweight champion Anderson
Silva. “The Spider” dispatched Bonnar in the first round,
dropping “The American Psycho” with a knee to the body and
finishing him off with ground-and-pound in 4:40.
Bonnar, who recently announced his retirement from active
competition, previously tested positive in 2006 for a Boldenone
metabolite after his UFC 62 rematch with Forrest
Griffin. The 35-year-old veteran was suspended nine months and
fined $5,000 by the Nevada Athletic Commission after that
infraction was discovered.
Herman, meanwhile, was submitted by Antonio
Rodrigo Nogueira in the evening’s pay-per-view co-headliner,
tapping to a “Minotauro” armbar with just 29 seconds remaining in
the second frame.
As with Bonnar, this also marks the second time that Herman has
been flagged, as he was previously pulled from a UFC 136 matchup
with Mike Russow
one year ago when he tested positive for marijuana in a pre-fight
drug screen administered by the Texas Department of Licensing and
Regulation. Herman later denied using the substance.
