Marks (foot) wasn't spotted at practice Wednesday, Jonathan M. Alexander of the Houston Chronicle and Aaron Wilson of KPRC 2 Houston report.
Marks exited Sunday's win over the Colts due to a foot injury, but was able to return to the contest en route to logging 41 snaps, 19 carries and a catch. With no setbacks having been reported since then, there's a solid chance that Marks' absence is maintenance-related, a notion echoed by coach DeMeco Ryans, who, according to Wilson, indicated that Marks was among the Texans' Wednesday DNPs who will be fine for Sunday's game against the Chiefs.
