Last roll of dice for playoff hopefuls

The National Football League's last four playoff berths will be decided by Sunday's final regular-season games, two of them showdowns in which the winner advances and the loser is done.

Chicago entertains Green Bay and Philadelphia will visit Dallas with the winner in each capturing a division crown and first-round home playoff game and the loser seeing their season conclude.

Dallas quarterback Tony Romo, who has a herniated disk in his back, is likely to be replaced by Kyle Orton when the Cowboys play host to the Philadelphia Eagles to decide the NFC East champion and a playoff spot.
