Green Bay, WI (SportsNetwork.com) - Green Bay Packers cornerback Sam Shields is questionable for Monday night's game against Atlanta.

Shields has not been medically cleared following a concussion he sustained last week against the Patriots.

"The medical staff has told me he still has a chance to play," said Packers coach Mike McCarthy on Saturday.

Shields has 30 tackles and two interceptions in 10 games this season.

If Shields can't go Monday, Green Bay has capable backups in Davon House and Casey Hayward.
