Pretrial motions will be heard beginning May 14. The NFL Players Association filed a federal lawsuit against the NFL on the players' behalf in December, hoping to overturn their four-game suspensions for violating the league's policy on steroids and related substances.
All five players tested positive for a banned diuretic, bumetanide, which they claim was an unlisted ingredient in an over-the-counter weight loss product called StarCaps.
The NFLPA is arguing that the league knew StarCaps was a tainted product but failed to properly warn players, and that the league-appointed arbitrator who ruled on their suspensions had a conflict of interest.
