Zombo, a rookie linebacker who stepped into the lineup for good in Week 8 after injuries landed four others on injured reserve, sustained a knee injury during a Week 14 loss to the Detroit Lions and hasn't played since.
The Packers had several players limited at practice, but virtually all of them have been listed as such each week but then played. That includes four starters -- defensive ends Cullen Jenkins (calf) and Ryan Pickett (ankle), linebacker Clay Matthews (shin) and cornerback Charles Woodson (toe). Running back John Kuhn (shoulder) and offensive lineman Jason Spitz (calf) also were limited Thursday.
Starting left tackle Chad Clifton (knees) fully participated after being limited Wednesday.
