GREEN BAY, Wis. (AP) Starting cornerback Sam Shields and rookie Quinten Rollins are doubtful for Green Bay's road game against the unbeaten Carolina Panthers on Sunday.

The Packers downgraded them from questionable on Saturday. Shields injured his shoulder and Rollins hurt his neck during the loss at Denver and didn't practice this week.

They each have a team-leading two interceptions.
