Matthew Riddle tested positive for marijuana metabolites following his bout at UFC on FUEL TV 7 in London, England on February 16, 2013. This is Riddle’s second failed drug test for marijuana within the past seven months. Riddle previously failed a post-fight drug test due to marijuana following his UFC 149 victory over Chris Clements.
As such, the UFC organization is exercising its right to terminate Riddle for breach of his obligations under his Promotional Agreement as well as the UFC Fighter Conduct Policy. The UFC organization has a strict, consistent policy against the use of any illegal and/or performance-enhancing drugs, stimulants or masking agents. The outcome of the bout against Che Mills was changed to a no contest and the results of the positive test will be reported to the official Association of Boxing Commissions MMA record-keeper.
