Green Bay Packers quarterback Aaron Rodgers was officially ruled out of Sunday's game against the visiting Pittsburgh Steelers.
Rodgers, recovering from a broken collarbone that has sidelined him for the past six weeks, took part in limited practice Friday but still has not been medically cleared to play.
"As an organization we do not feel like we are ready for him to play," coach Mike McCarthy said. "He's not medically cleared, that's still the case today. As an organization, we don't think this is the right time for him to play."
Matt Flynn will start Sunday's game for the Packers (7-6-1), who are a half-game behind the Chicago Bears (8-6) in the NFC North. The Packers visit the Bears in the regular-season finale Dec. 29.
McCarthy declined to provide details on the decision making process regarding Rodgers' return, or who the final decision ultimately falls to, offering only that he "absolutely" agrees with the decision.
