Williams (toe) had just one carry for four yards, was charged with a fumble, and didn't draw a target in the passing game in a 42-21 win over the Steelers.
Clyde Edwards-Helaire (shoulder) missed his third straight contest, but it was Jerick McKinnon who drew the start took over lead-back duties instead of Williams. Perhaps the 26-year-old -- who was listed as questionable heading into the contest -- was not as ready to play as pregame reports indicated, resulting in a underwhelming usage and a poor fantasy showing. He was effectively benched for the remainder of the contest after he was involved in a sloppy handoff from Mecole Hardman that resulted in a fumble that was scooped up by T.J. Watt and returned for a Steelers touchdown. The status of Edwards-Helaire is still uncertain for next round's tilt against the Bills, but McKinnon looks like the hot hand among Kansas City's remaining backfield options for the time being.
