Sharper suffered a bruised chest Nov. 23 against the San Francisco 49ers, landing hard on his back after breaking up a pass. He is expected to practice in non-contact drills next week when the Packers prepare for the Bears.
Marques Anderson, who started in Sharper's place on Thursday, suffered a mild concussion during the Lions game. He was cleared by doctors after the game and is expected to be ready to play against the Bears.
Barnett tested his sore right ankle that he injured against San Francisco during warmups prior to Green Bay's game against the Lions, but coach and general manager Mike Sherman decided to rest the rookie. Sherman said Barnett, the team's leading tackler with 102, "will be ready" for the Packers' upcoming game.
It is uncertain at this time if safety Antuan Edwards (hamstring) and linebacker Paris Lenon (quad strain) will be ready to go against the Bears. Both players suffered the injuries against the Lions. Edwards underwent a magnetic resonance imaging test this afternoon to determine if there is further damage to his hamstring.
