NFL Network's Omar Ruiz reported Johnson has been fully cleared from the wrist injury that barred him from all but 43 plays during the 2017 season.
Johnson exited the season opener with a broken wrist and subsequently underwent surgery. The 26-year-old running back went on injured reserve. Despite early optimism Johnson might return, he never made enough progress following surgery.
Johnson declared himself fully healthy in January, and new coach Steve Wilks expected the running back ready to go for workouts.
Getting the dual-threat Johnson on the field for the full slate of offseason workouts is a boon to Wilks and his run-heavy game plan heading into the 2018 campaign.
