The Panthers waived Johnson on Monday, Darin Gantt of the team's official site reports.
Johnson impressed during Carolina's most recent preseason game, touching the ball 20 times for 83 total yards and one touchdown, but it now appears that the team has decided to part ways with the 23-year-old. Now that Johnson has been waived, Carolina's running back room consists of Chuba Hubbard (knee), Jonathon Brooks (knee), Miles Sanders, Raheem Blackshear, Mike Boone and Jaden Shirden.
