Dallas Cowboys linebacker Rolando McClain has yet to report to training camp, and there are real questions as to whether or not he will ever play in the NFL again.  Sources confirmed that McClain’s recent 10-game suspension is not for a failed marijuana test but for an opiate commonly referred to as “purple drank.”  I’m sure you’ve heard of it from several rappers ahem “Dirty Sprite”, a mixture of Sprite, cough syrup and codeine.  McClain is reportedly addicted to codeine.
