What has already been a bad offseason for the Dallas Cowboys defense just got worse. According to multiple sources, defensive end Randy Gregory violated the NFL's substance abuse policy again and now faces a longer fine.

Gregory is already facing a four-game ban to begin the season, but he could miss the first 10 games after his latest alleged violation. ESPN reported that it is not known if Gregory either missed a test or failed a test. According to the rules of the NFL's substance abuse policy, the two are treated the same.

The Cowboys will also be without their sack leader, DeMarcus Lawrence, for four games and linebacker Rolando McClain will miss 10 games. Both players violated the league's substance abuse policy. Gregory, Lawrence, and McClain can all take part in training camp and preseason games. Gregory will not be allowed to practice with the team. Training camp opens up on Thursday in Oxnard, California.
