Randy Gregory has apparently messed up again.
The Dallas Cowboys defensive end -- who slipped to the second round of the 2015 NFL Draft after testing positive for marijuana at the NFL Combine -- has been suspended for the first four games of the 2016 season, an NFL spokesman told FS1 NFL Insider Mike Garafolo.
Gregory's suspension comes for a violation of the league's substance-abuse policy. Gregory's rookie season wasn't a smooth ride as he got hurt in the regular-season opener and didn't return until Week 7. He finished the season with 11 total tackles and zero sacks.

The league also announced two other suspensions on Friday. Baltimore Ravens tight end Nick Boyle was suspended 10 games for a performance-enhancing drug violation, while Green Bay Packers defensive tackle Mike Pennell was dinged four games for a substance-abuse violation.
Both players will be eligible to participate in all offseason practices and preseason games.
