Harrison initially exited in the first half of Week 6's loss to the Indianapolis Colts and did not return. He then spent the week in protocol and was spotted wearing the league's yellow non-contact jersey before shedding it on Friday, paving the path to play.

Harrison suffered a concussion last Sunday, in Indianapolis, when his helmet struck the turf.

The Packers must keep him out of the backfield or he'll create disruptive plays.
