The Packers are confident that wide receiver Greg Jennings will play in the NFC divisional playoff game the weekend of Jan. 14-15 at Lambeau Field. Jennings apparently has made a strong recovery from the sprained medial collateral knee ligament that he suffered 13 days ago against Oakland. "Greg Jennings will be challenged to play next week against Detroit," coach Mike McCarthy said. "But I don't think there will be any question that he will play in the playoffs. That's the early diagnosis based on talking to the medical staff."
