KANSAS CITY, Mo. — Chiefs coach Andy Reid is planning to give running back Isiah Pacheco most of the week off to rest his sore ribs. Reid hasn’t decided who else will get time off before their regular-season finale in Denver. The Chiefs (15-1) already have clinched the No. 1 seed in the AFC playoffs, and with it the lone first-round bye, rendering their game against the Broncos meaningless to them.
