The Redskins-Cowboys game next Sunday at FedEx Field was rescheduled for 8:20 p.m.  on NBC under the sport’s flexible scheduling arrangement.

The game will decide the NFC East title.

The announcement was made Sunday evening, hours after the Redskins’ triumph at Philadelphia. Cornerback DeAngelo Hall said after the win over the Eagles that he hoped the Redskins-Cowboys game would be moved to Sunday night.

“Absolutely,” Hall said. “We want to be the only show on TV. That’s a good feeling. Prime time, baby.”

Asked what he expects, Hall said: “Pandemonium at FedEx Field. The way you like it. It’s definitely going to be a playoff atmosphere. We encourage the fans to get on out there early. Let’s go ahead and flex this game. And we’ll make it real nice.”

The Redskins have won six straight games to improve their record to 9-6. But if they lose to the Cowboys, Dallas will capture the division title. And the Redskins, under that scenario, would need help in other games to reach the playoffs as a wild-card team.

With the prime-time kickoff, the Redskins will know when they take the field whether it’s an all-or-nothing game for them.

They could clinch a playoff spot earlier Sunday if the Bears and Vikings both lose, in which case Washington will be playing to see if it is the division champ or a wild-card team. Or, if either Bears or Vikings win, the Redskins will know they must win the game and with it the division title or miss the playoffs entirely.

“We’re not done yet,” Hall said. “All this means nothing if we don’t go out next week and do what we need to do.”
