UFC 153 fighters Stephan Bonnar (15-8) and Dave Herman (21-5) each tested positive for banned substances in their post-fight drug screens.

MMAjunkie.com today confirmed with Ultimate Fighting Championship officials that all 24 fighters who competed at this past month’s UFC 153 event in Brazil were tested, and Bonnar and Herman were the lone two competitors who failed the screen.

Bonnar tested positive for Drostanolone, an anabolic steroid, while Herman’s screen was flagged for marijuana metabolites.

UFC 153 took place Oct. 13 at Rio de Janeiro’s HSBC Arena. Anderson Silva defeated Bonnar in the evening’s headliner while Herman was submitted by Antonio Rodrgio Nogueira in the co-main event.

With the lack of an athletic commission to govern the event, UFC officials took the role of overseeing the fight card. UFC exec Marc Ratner said the company has yet to issue a suspension to the fighters but is expected to do so sometime next week.

Bonnar earlier this week announced his retirement. His first positive test and subsequent suspension came after UFC 62, at which he dropped a unanimous decision loss to Forrest Griffin in their rematch. At that event, the Las Vegas-based Bonnar tested positive for a Boldenone metabolite that resulted from anabolic-steroid use.

Following the suspension, Bonnar owned up to the infraction, saying he was trying to speed up the rehab of an injured elbow in time for the Griffin fight. He was suspended for nine months by the Nevada State Athletic Commission and fined $5,000.

After a three-fight losing skid that included unanimous decision losses to eventual light heavyweight champion Jon Jones and UFC Hall of Famer Mark Coleman, Bonnar bounced back in 2010 with a second-round TKO win over Krzysztof Soszynski, then dominant unanimous decision wins over Igor Pokrajac and Kyle Kingsbury.
