Stephan Bonnar And Dave Herman have both tested positive for banned substances following UFC 153 which took place in Brazil last month.

All 24 fighters that competed on the card were tested by UFC officials due to the lack of an athletic commission to oversee the event in Brazil. Bonnar tested positive for Drostanolone while Herman tested positive for marijuana metabolites.

UFC exec Marc Ratner said that suspensions have yet to be handed down but can be expected sometime next week.
