Lacy hasn't practiced since he sustained a concussion in Green Bay’s 36-16 loss to Seattle last Thursday. He had to go through the NFL's concussion protocol and be cleared by an independent neurologist before being allowed to return.
The running back returned to the field on Thursday and had a "normal practice," according to the Packers coach Mike McCarthy.
Lacy had 12 carries for 34 yards in the season-opening loss to Seattle.
