UFC middleweight Ed Herman spoke to Ariel Helwani on Monday on The MMA Hour and discussed his fight on Saturday with Ronaldo Souza in Strikeforce. He also talked about his most recent loss to Jake Shields. Herman believes there's strong indication Shields was on some form of performance enhancing drugs (PEDs). "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," Herman said.
