The NFL declined to comment on this matter.
Williams and Davis were two of 11 players who tested positive following the NFL lockout during the offseason. The players claim the NFL Players Association led them to believe that drug testing would not resume immediately after players reported to training camps.
But the testing did, in fact, begin shortly after the lockout ended. Many players were under the assumption there would be a 30-to-60-day buffer before testing started.
Once testing positive in August, the 11 players became part of the testing program, which made them subject to more testing. The drug levels found in Williams and Davis continued to escalate at times of testing, according to a source with knowledge of the situation, which explains why they are now facing suspension and the other nine players, at this point, are facing only fines.
Sports Illustrated first reported that Davis and Williams were informed earlier in the week that they would be suspended for the entire season because they tested positive for marijuana during the season, but the discipline was reduced as part of a negotiated settlement involving the 11 players.
