Sander on Monday said Barker had passed him on the depth chart. The two are splitting kicks at practice this week.
The initial injury report was released by the league on Wednesday.
Kenny Peterson, who suffered a sprained ankle and hyperextended knee during the Tennessee game, is listed as doubtful. Linebacker Torrance Marshall, who has been battling a hamstring injury for a couple weeks, is questionable. Listed as probable are running back Ahman Green (knee), wide receiver Donald Driver (ankle), cornerback Michael Hawthorne (back), tight end Steve Bush (ribs) and cornerback Jason Horton (hip).
Carolina has just one player on the list: Starting guard Tutan Reyes (ankle) is questionable.
Probable means the player has a 75 percent chance of playing, questionable is 50 percent and doubtful is 25 percent.
ROLL OUT THE GREEN CARPET
The Packers on Wednesday got their first taste of the FieldTurf playing surface installed on the Ray Nitschke practice field this summer. Sherman gave it rave reviews, saying the surface helps keep the players' legs fresh.
The faux grass won't be replacing Lambeau Field's famed sod anytime soon, though. "I can imagine the letters we would receive in regard to artificial surface on Lambeau Field," Sherman said.
The Packers' other outdoor practice field, Clarke Hinkle, will remain grass. In fact, the team is in the process of replacing the sod.
GREEN BAY CONNECTIONS
Green Bay's defensive line will face a tall order Monday night when they face Matt Willig. Willig, a resounding 6-foot-8 and 315 pounds, spent the 1998 season in Green Bay as a backup offensive tackle. On Monday, he will be starting at right tackle for Carolina.
"He's a big, tough guy with long arms, and he's a tough competitor. He's had a good (training) camp, and we feel comfortable with him at right tackle, Carolina coach John Fox said.
For Packers fans making the trek to Carolina, if you tune into the Panthers Radio Network and you hear a familiar voice, that would be former Packers safety Eugene Robinson.
