According to the good folks at NFL.com:
Saturday, 9 January
4:30 PM Eastern - New York Jets @ Cincinnati Bengals (NBC)
8 PM Eastern - Philadelphia Eagles @ Dallas Cowboys (NBC)
Sunday, 10 January
1 PM Eastern - Baltimore Ravens @ New England Patriots (CBS)
4:30 PM Eastern - Green Bay Packers @ Arizona Cardinals (FOX)
As far as the NFC, the Vikings will host the highest remaining seed. So, if Dallas beats Philadelphia, the other game doesn't matter. . .the Cowboys will come to the Metrodome to face the Vikings. If Philadelphia wins, then we'll automatically host the winner of Packers/Cardinals.
Should be an interesting weekend, to say the least. The only team we can't potentially face in the Divisional playoffs is the Eagles.
