Kansas City lost its fourth game of the season on Sunday in its first without a key veteran presence.
"LeSean's not getting any younger so it's important I manage him the right way as we go," Reid told reporters, per ESPN's Adam Teicher.
NFL Network's James Palmer reported prior to the game that this was a predetermined rest week for McCoy, who after Sunday's loss has played on 35.6 percent of Kansas City's offensive snaps (191). McCoy has 92 touches for 500 total yards and three scores in nine games played this season, his first with K.C.
As Reid intimated, "load management" could be Kansas City's new reality, treating the veteran McCoy as the NBA's Clippers do Kawhi Leonard. The 6-4 Chiefs have visions of a deep playoff run, meaning they need McCoy and the rest of their roster to be well rested and healthy-ish into the throes of winter.
If that means sacrificing McCoy's availability for a game or two, and potentially sacrificing a win, so be it.
