Armando Salguero: This NFL Sunday, Four Teams Are Playing For Bye In AFC, And Two Division Champions Will Be Decided

The NFL's playoff seedings are almost set -- but not quite. We know most of the division winners -- but not all.

So let's break down what we know for certain and what can still happen in the 18th and final week of the NFL regular season on Sunday to affect the postseason:

AFC

Five of seven spots have been clinched.

NFC

Six of seven spots have been clinched.

So the top seed in the NFC is decided in that the Green Bay Packers get the only first-round bye and will host games as long as they continue to advance.

Although the Tennessee Titans currently hold the top seed in the AFC, the spot can still be won by four different teams -- Tennessee, Kansas City, New England or, amazingly, Cincinnati.

The AFC West, AFC North and AFC South have their champion.

The NFC North, NFC East, and NFC South have their champion.

That means two division champions will be decided on Sunday: The AFC East, and NFC West.

So this is what can play out in the AFC with Sunday's results:
