"I think Colorado is one of the HIPAA privacy states where they weren't allowed to release what he tested positive for," Herman said of Shields. "I'm pretty sure it was for some type of performance enhancing substance, just by looking at his physique going in to the fight. He looked pretty puffed up and exhibited the common signs. As an athlete, you can recognize those signs. I can't guarantee it, but I'm pretty positive that it was for some kind of performance enhancing drug. If it really was for marijuana, it's a lot easier for a guy to come right out and say, 'I smoked a joint, sorry.' You get a little less criticism that way than if you cheated and used a performance enhancer."
Herman's loss to Shields was overturned to a no contest because the latter failed a post-fight drug test.
For Herman's next fight, he takes on Ronaldo Souza on Jan. 12 in the final Strikeforce event.
"It does feel like I'm gonna be a part of a historic event," Herman said of fighting for Strikeforce. "At first I was like, 'Aw Strikeforce? That's a downgrade,' but now that I've thought about it, I'm actually pretty excited and honored to be a part of this last event. I can always say that I'm a Strikeforce vet, as well as a UFC vet. This card is stacked, too. I'm pumped and I think it's gonna be great."
