Acccording to NFL Insider’s Ian Rapoport, the suspension means that Gregory has now failed four drug tests — the first being the combine test. The second resulted in him being fined two games’ pay, the third in four games’ pay, and the fourth is this four-game suspension. Should Gregory fail another drug test he will face a half-season ban.
After missing the first four games of the 2015 season due to a high ankle sprain suffered in Dallas’ season opener, Gregory had a fairly quiet rookie campaign, racking up 11 tackles and 16 quarterback hurries throughout the remaining 12 games.
Gregory will still be eligible to participate in all of the Cowboys’ offseason workouts and preseason games.
