Two of the six suspended NFL players respondTwo of the six players suspended by the National Football League (NFL) for testing positive to drugs are about to challenge the ruling.

The NFL suspended defensive tackles Pat Williams and Kevin Williams of the Minnesota Vikings, a trio of players with the New Orleans Saints – running back Deuce McAllister and defensive ends Will Smith and Charles Grant – and centre Bryan Pittman of the Houston Texans for violating the league’s policy on anabolic steroids and related substances.

The drug in question is Bumetanide, which is a diuretic that can mask the presence of other substances, including steroids.
