The real worry, per Rapoport, is that Gregory has shut out people in his inner circle. It's now hoped that treatment will help him resolve the problem and allow him to get his football career back on track.
A consensus top-10 talent leading up to the 2015 NFL Draft, Gregory plummeted to Dallas in the second round due to a failed drug test at the NFL Scouting Combine. The Nebraska star also was late to pre-draft interviews amid concerns about his ability to handle the "mental rigors" of professional football.
Executive vice president and chief operating officer Stephen Jones made it clear months ago that the second-year edge rusher was on thin ice.

The front office is under increasing pressure to import pass rushing help over the next six weeks.
