Washington Commanders (3-4) at Kansas City Chiefs (4-3). From GEHA Field at Arrowhead Stadium. The prime-time Chiefs go under the lights for the fifth time in eight games, with QB Patrick Mahomes rounding into form in averaging 31.5 points over the last four games. Washington has struggled defensively to go with a banged up offense that again turns to QB Marcus Mariota. K.C. is 10-1 in the series.
