Game planning in Dallas must be interesting. Aaron Rodgers isn't the only Green Bay Packers starter in limbo.

Running back Eddie Lacy, who played through a sprained right ankle last week, didn't practice Wednesday. Coach Mike McCarthy indicated the rookie would continue rehabilitating Thursday and could practice on Friday.

So as Lacy tries to regain strength and stability in the ankle, the only other healthy ball carriers on the roster are James Starks, Kahlil Bell and fullback John Kuhn.

Rodgers' return may be of utmost importance for the Packers, but Lacy has accounted for 62% of the team's rushing attempts this season and his 887 yards rushing and club rookie-record seven touchdowns are representative of how much of the offense has gone through him.

McCarthy sounded cautiously optimistic about Lacy's return, but if the ankle becomes an issue, Starks and Bell would have to pick up the slack.

Despite the Packers wanting to get Starks involved more, the fourth-year pro has 18 carries his last five games. He averaged 2.7 yards per carry against Atlanta. Bell, signed last week off the street, does not have a carry.

"Kahlil Bell is doing a hell of a job," McCarthy said. "I'm hopeful he'll be ready to play if needed. I like what I've seen. Sharp, done a good job on special teams, he's picked up the language fairly well. He's done a good job in his short time."

Since his Week 2 concussion, Lacy has been extremely durable. Absorbing weekly punishment — 20-plus carries in eight of his last 10 games — he has stayed healthy. But on the final play of the first half Sunday against Atlanta, Lacy bounced outside and rolled his ankle.

Lacy was able to return after a thorough tape job, and his ability to break tackles kept Green Bay in manageable down and distances.

"Great. He played great," McCarthy said. "I was really impressed with him. The run blocking, we weren't at our best, but he broke a number of tackles. I don't recall exactly what the number was off our stat sheet, but I thought he ran hard. He played very well."

By staying cautious, Green Bay hopes he'll be able to go Sunday.

Inside job: Neither Brad Jones (ankle) nor Jamari Lattimore (knee) took part in practice, leaving A.J. Hawk and first-year pro Victor Aiyewa to man the two inside linebacker positions.

Behind them there is nobody else.

"I feel good about Brad and Jamari," McCarthy said. "The practices, we'll be smart with them throughout the week. Our medical staff was pretty confident with that."

Also sitting out practice were linebacker Mike Neal (abdomen) and end C.J. Wilson (ankle). Neal has been taking one or two days off each week to rest his body and is expected to play. Wilson has been inactive the last two weeks.
