One player currently on the roster is no longer going to be a Packer, at least for the rest of this season.
If the Packers decide to activate defensive tackle Justin Harrel from the physically unable to perform (PUP) list, they'll have to either cut a player or put one on injured reserve (IR), ending their season.
It's possible that a player can be put IR, but the Packers seem to be getting more healthy by the minute. Unless they deem Al Harris should not be playing the rest of the season, it would be hard to believe any other Packer would be shut down.
Perhaps the Packer most at risk of being cut would be punter Derrick Frost, but they would have to fill his absence with that of another punter, so that's not a possibility.
Cornerback Jarrett Bush would seem the next most likely candidate. With Al Harris coming back, the Packers have some depth in the defensive backfield and Bush would be more expendable. It's next to certain the Packers wouldn't cut second round draft choice Pat Lee ahead of Bush even though Bush has seen more playing time this season.
Bush has been a key special teams contributor and the Packers would miss his production there.
The Packers also have an opening on the practice squad after defensive end Rudolph Hardie was released. Expect these holes to be filled early next week.
