The Packers have ruled out Aaron Rodgers for Sunday's game against the Pittsburgh Steelers. It will be Green Bay's seventh straight game without Rodgers since the franchise quarterback fractured his left collarbone during the first series of a 27-20 loss to the Bears on Nov. 4. Backup Matt Flynn will make a fourth straight start. Coach Mike McCarthy said Friday that Rodgers has not received medical clearance yet, and that the organization feels Rodgers is not ready to play.
