BEREA, Ohio -- An already-shorthanded Texans running back room took another hit Sunday when Woody Marks was ruled out with a concussion sustained against the Browns.
Marks was hurt on a third-down carry in the third quarter with Houston ahead, 17-10. Browns defenders Emmanuel McNeil-Warren, Sam Kamara and Quincy Williams collided with Marks, who didn't get up for a few minutes.
He eventually left the field with Texans athletic trainers.
Marks had 12 carries for 50 yards before exiting. Running backs Emari Demercado and Dare Ogunbowale also had carries Sunday.
Houston came into Week 10 without running back David Montgomery, who's still dealing with a groin injury suffered in Week 4. Montgomery practiced this past week, but a team source described his activity as a ramp up ahead of a potential return Thursday against the Indianapolis Colts.
With the Texans on a short week, Marks will have to clear the concussion protocol quickly in order to face the Colts.
