Dallas Cowboys defensive end Randy Gregory is expected to apply for reinstatement to the NFL by next week, Kate Hairopolous and Jori Epstein of the Dallas Morning News report.

Gregory hasn’t played in the NFL since the Cowboys’ final regular season game of the 2016 season as he served a one-year suspension for violating the league’s substance abuse policy.

“He’s being very diligent in preparing his information and preparing his application,” owner and general manager Jerry Jones said Wednesday at the team’s annual tournament at Cowboys Golf Club. “I have been proud of Randy during this offseason. I’m very aware of how hard he’s working to get back in the league and get back on the field.”

Cowboys teammates Tyrone Crawford, Sean Lee, and Jeff Heath have reportedly given written statements to the league on Gregory’s behalf.

If the application is filed by next week, commissioner Roger Goodell could have a decision on Gregory’s reinstatement before Cowboys training camp begins in the last week of July.

Dallas drafted Gregory in the second round of the 2015 NFL Draft. He likely would have gone higher had he not failed a drug test during the Draft Combine. He has also appeared in just 14 regular-season games due to multiple drug-related suspensions. He has recorded 20 tackles with one sack in those 14 games.

If Gregory is successfully reinstated by the league, he would join an already deep Cowboys defensive end depth chart which includes DeMarcus Lawrence, Tyrone Crawford, Taco Charlton, Kony Ealy, Datone Jones, and Charles Tapper.
