It does seem strange that he pulled out of the fight as this story broke. Also seems strange he's been so vocal about PED use after the meeting in Sept last year about the investigation of his possible doping. Already laying the ground work to lower suspicion and to bolster any claims of being clean.
Remember when people were asking why Hugie has this insane acne on his chest and back, and if this was related to PEDs? I guess they were on to something.
