Lee sprained his left knee during Sunday's game against the Bears, and his availability for the Week 3 game at Indianapolis is uncertain. Lee started Sunday because of the dislocated left kneecap suffered in the opener by Jackson.
"I guess I just stepped wrong and heard something go crunch," Lee said. "So, I just got to rehab it right now, today and tomorrow and see how it is."
If Lee can't go, then the onus falls on Jenkins to plug the middle as best he can against the juggernaut Colts offense. As you'd expect from players their size, Jenkins is more adept at making plays with his quickness while Lee is better suited to controlling the line of scrimmage. Whatever happens, Jenkins says he'll be ready.
"I'm comfortable always to play any position on the D-line. So, if it came down to it, yeah ...," Jenkins said about possibly starting.
On the bright side, second-year defensive lineman Kenny Peterson may be ready to play after injuring an ankle and knee in the preseason finale at Tennessee. There is no practice Tuesday, and Sherman is hopeful Peterson can participate Wednesday.
Whoever lines up, the Packers need better production. While Packers coach Mike Sherman said Lee and Jenkins shouldn't be blamed for the Packers' porous run defense against the Bears, the veteran Jackson is irreplaceable because of his size and experience.
"Grady would have made more plays than maybe those guys because he's a better player at this stage of his career than they are," Sherman said. "But at the same time, they did their jobs. ...
"I can't fault them for what happened in regard to the ground game," Sherman added in regard to the Bears rushing for 182 yards.
In other injury news, starting linebacker Hannibal Navies and backup tight end David Martin may not participate when the Packers hit the practice field Wednesday. It could be a repeat of last week, when both were limited in practice but played in the game. Navies has a strained left shoulder while Martin is slowed by a bruised left quadriceps.
Backup halfback Najeh Davenport may be able to practice Wednesday, Sherman said. The Packers running game did fine without Davenport, who is battling a strained right hamstring, but the kickoff-return team was a shambles, with Antonio Chatman and Ahmad Carroll failing to deliver in his place Sunday.
