When Paulie, known for accusing Pac of PEDs, was asked whether the thought of Khan also using PEDs had crossed his mind, he said: "I would be lying if I told you that I wasn't a little suspicious. I haven't seen enough of Amir Khan to put a judgement on that so to speak. [.......] Amir Khan is in the same stable (as Manny) and that's the only reason I have my suspicions. [.......] Other than that, I don't suspect Amir Khan of anything." Khan in return said: "I'm not scared of needles, if you want me to take a drug test, I'm happy to do that for you."
There is that chance but it's highly, highly unlikely. In that fight we didn't get to see much of Prescott because it lasted less than a minute but against Mitchell Prescott was horrible. That fight showed how one dimensional and sloppy he really is.
