GREEN BAY, WI (WHBL) - The Green Bay Packers say they'll have to guard against overconfidence, now that quarterback Aaron Rodgers is returning. Coach Mike McCarthy said Thursday that Rodgers has been medically-cleared to start Sunday's contest at Chicago for the N-F-C North Division title. The Packers are 2-5-1 since Rodgers broke his left collarbone on November fourth. McCarthy said he won't put the entire game on Rodgers' shoulders. Guard T-J Lang said Rodgers is a difference-maker, but it does not mean the other players can slide now that he's back. Rodgers said the recovery has been difficult for him because he thought he had a chance of returning every week since his injury. Lang called Sunday's contest a playoff game for the Packers. If they win, they'll make the post-season. If they lose, their season is over.
