Campbell understood he likely was signed in August as an insurance policy in case something should happen to safety Raven Greene, who played the hybrid linebacker spot with the starting defense throughout the offseason program.

Greene got off to a great start against Chicago in Week 1, recording five tackles with a deflection, before suffering an ankle injury the following week against Minnesota. The injury landed Greene on IR and forced Pettine to reshuffle his defensive deck.

That resulted in Adrian Amos, Will Redmond and Josh Jackson all filling in at times next to linebacker Blake Martinez in that hybrid package the past two months. Based on Campbell's skill set and history with Pettine, the Packers believe the returning safety could potentially help settle that spot.

"It's just been kind of a revolving door," Head Coach Matt LaFleur said. "We've had to put a lot of different people in different spots and I think this will help us in terms of allowing guys to stick to one spot, and maybe be a little bit sharper on the details so we can go out and play a little faster."

Campbell, now 11 months removed from surgery and confident again in the knee, doesn't make too big a deal out of whether he's playing deep or in the box. He believes his tools enable him to fill both roles.

The past three months have been beneficial, though. They not only gave the safety closure with his rehab, but also allowed Campbell a chance to get acclimated to Green Bay's locker room after a whirlwind November in 2018.

His return couldn't have come with better timing for the Packers, who host the Carolina Panthers and MVP candidate Christian McCaffrey on Sunday. What's more, Amos missed practice Wednesday with a hamstring injury. He's played 596 of a possible 600 defensive snaps so far this season.

Campbell is ready to do whatever is asked of him. No different than the circumstances he faced as a waiver claim last year.
