The Cowboys won’t have the services of Randy Gregory in the playoffs, or for the next regular season, either. The second-year defensive end received a one-year suspension without pay from the NFL Thursday for his latest violation of the league’s substance-abuse policy.

Gregory played just two games this season, in Weeks 16 and 17, following a four-game suspension to start the season and a 10-game ban issued after he failed a drug test while sitting out those first four games. He reportedly failed another test in November, then attempted to appeal his suspension on Tuesday, to no avail.

The Cowboys took Gregory with the 60th overall pick in the 2015 NFL draft, getting the talented Nebraska pass-rusher that late because of concerns about substance abuse. Those concerns sprang from the fact that he failed a drug test during the league’s draft combine, later saying that avoiding marijuana use had “been a struggle” for him in the past, but that he hadn’t consumed any since December 2014.

Gregory managed to get through his rookie season without incident, although he missed four games with an ankle injury and failed to record a sack while being used sparingly. The 6-foot-5, 255-pound edge rusher finally got his first career sack in the Cowboys’ regular season finale last week against the Eagles, but it is fair to wonder if he will still be on Dallas’s roster when his suspension ends.

Cowboys owner Jerry Jones was willing to take a chance on Gregory’s talent, but Gregory will enter the final year of his rookie contract having played just 14 games, with eight tackles and the one sack. According to NFL Network’s Ian Rapoport, Gregory can apply for reinstatement on or after Nov. 6.

Gregory’s first suspension was announced in February 2016 and was the result of his fourth failed test while in the NFL, including the one from the combine. In July, he checked into a drug treatment facility and missed the Cowboys’ training camp.
