As you might recall, five NFL playersKevin and Pat Williams of the Minnesota Vikings and Charles Grant, Deuce McAllister, and Will Smith of the New Orleans Saintswere suspended for four games last year after testing positive for bumetanide. Bumetanide, a diuretic, is banned under the NFL Policy on Anabolic Steroids and Related Substances (the NFL Policy) because it can be used to mask the presence of steroids.
