Chiefs seek top seed in holiday test for playoff-bound NFL teams

The Chiefs, with an NFL-best 14-1 record and seeking a Super Bowl three-peat, can secure the AFC top seed with a triumph over the Steelers (10-5) while Baltimore (10-5) is at Houston (9-6) in a possible first-round playoff preview. The Christmas double-header, in the penultimate week of the campaign, will mark the first NFL games shown by streaming giant Netflix. Chiefs quarterback Patrick Mahomes has shaken off a high left ankle sprain suffered December 15, showing no signs of trouble in a victory last Saturday over Houston.
