Defensive end Demarcus Lawrence faces a four-game suspension for violating the NFL’s substance-abuse policy. Lawrence will appeal the suspension. The Cowboys defensive end has already been fined for an initial positive test now he faces suspension. He will be the second Dallas Cowboys defensive end to face suspension. Randy Gregory was suspended for violating the league’s policy, earlier this offseason. This will likely put a damper on the Dallas Cowboys pass rush as they will be without both of their starting pass rushers the first four games of the season.
