Riddle tests positive for marijuana, released by the UFC

The welterweight fighter on Tuesday confirmed to MMAjunkie.com Radio (www.mmajunkie.com/radio) that he failed his second post-fight drug test for marijuana and has been released from the UFC.
Riddle flunked a test following UFC on FUEL TV 7, where he earned a split call against Che Mills (15-6 MMA, 2-2 UFC). Both fighters now cut by the organisation.
