Assuming the Oxy rumors are true, I don't see it being enough to terminate his contract. Richards has endured an extreme amount of physical abuse over his career, it shouldn't be surprising if we assume he was taking or addicted to pain killers. Yes it is serious, but even still, this would not be something he would be terminated for, even if he was driving a Mack Truck filled with them through the border. If there isn't anything more to the story, I don't see them having a leg to stand on when the NHLPA inevitably appeals.
