Five of the seven AFC playoff spots are secured, with five teams fighting for the final two conference tickets to the postseason in Week 18.

The Baltimore Ravens, Los Angeles Chargers, Las Vegas Raiders, Indianapolis Colts and Pittsburgh Steelers enter the final weekend of the debut 17-game regular season with a shot at the expanded playoffs. Seven teams in each conference will make this month's postseason field in an NFL first.

Only one spot is open in the NFC with the Green Bay Packers locked into the No. 1 seed and lone first-round bye with a dominant victory over the Minnesota Vikings on Sunday night.
