‘Smith failed a test last November. He said he has no idea why. His appeal under the terms of the drug policy with the NFL and the NFL Players Association fell on deaf ears. “It was absolutely unintentional,” Smith said. “I actually don’t ever take supplements that I personally buy. I only take supplements given to me by the team. So I still to this day don’t know where this positive test came from. No one really, the NFLPA included, has really helped me to figure it out.”’
