The Panthers signed Johnson on Wednesday, Mike Kaye of The Charlotte Observer reports.
The Washington product was dropped by the Titans just two days ago, but he's already found a new home in Carolina. Johnson has a shot to make the Panthers' 53-man roster, as the team's No. 3 running back spot is seemingly open. Once Johnson arrives in Carolina, he's expected to compete with Miles Sanders and Raheem Blackshear for a depth role on the Panthers' offense.
